1)Homayoun Bagherinia, Roberto Manduchi,had proposed the for University of California, Santa Cruz”A novel approach for color barcode decoding using smartphones”
The use of colors increases the information storage capacities in barcodes. Increasing the number of color stolen code information makes the decoding a challenging task due to the dependency of the surface color on the illuminant spectrum, viewing parameters, printing device and material. The decoding becomes more challenging if a mobile phone as a decoding device is used due to the capture of image from different distances as well as angles. We present an iterative decoding algorithm that decodes the colors of all barcode patches across the barcode by

5) Amin Motahari , Member, IEEE, and Malek Adjouadi , Member, IEEE had Praposed the work for “Barcode Modulation Method for Data Transmission in Mobile Devices” In this study, a new approach for data modulation in 2-D barcodes is introduced, and its performance is evaluated in comparison to other standard method of barcode modulation. In this new approach, orthogonal frequency-division multiplexing (OFDM) modulation is used together with differential phase shift keying (DPSK) over adjacent frequency domain elements. A specific aim of this study is to establish a system that is proven tolerant to camera movements, picture blur, and light leakage within neighboring pixels of an LCD.
III. THE PROPOSED PICODE SYSTEM In this section, the proposed PiCode system is described with an emphasis on the novel aspects of the image modulation and demodulation process. For the modulation part the details of the modulation scheme will be presented to illustrate how PiCode preserves the perceptual quality of the embedded image while minimizing the interference of the latter incurred on the modulation waveform. For the modulation part, the algorithms for performing discrete cosine transform, block division will be described.
A. Image modulation
The various steps in image modulation are
• Input image and message
• Convert RGB to YUV
• Block contrast
• Divided into inner and outer
Why is the color bar so important in the salon? One of the many reasons why it’s so important is because color is a hair treatment that continually brings people into the salon. you’ll will see a guest two more times a year than someone that comes into get just a haircut. The color bar helps make loyal costumers daily. Every costumer that comes in to get their hair colored have to make appointments after their first hair color to make sure they keep the color refreshed and get root touchups. Hair color is one of the more expensive treatments that people get done with their hair . Color sales are in the billions. Having a good color system and good stylists that are good at color not only make more money for the stylist but also brings in
Using this wireless technology makes it harder to control the content viewed, especially when personal computers can access the network. RFID can typically be a more expensive technology than your normal barcoding system. You can choose between using active RFID tags or passive RFID tags. Passive tags are very similar to a barcode; however active tags can be activated to track movement and count in a quick manner. Active tags are more expensive, but certain types can be reused. RFID tags can also be larger than a regular barcode and can be more difficult to understand than a typical system. Also, “Some common problems with RFID are reader collision and tag collision.” (What is RFID?, 2012) These types of collision occur when multiple readers or tags are in one area making it difficult to pick up the correct signal.
Table I displays six solid binary images along with their corresponding compression ratios. On considering Run-Length coding, the alternative encoding scheme produces better performance than the other encoding scheme. On an average, the proposed algorithm performs well on comparison with the standard Huffman coding algorithm by approximately 1.58%.
The Color Code profile was created by Dr. Taylor Hartman, who believed that precise are divided by four colors. Throughout his research studies and experiences that he conducted over the years he assigned individuals to a specific color based on their personality, behavior, and actions. The four colors that Hartman used for the color code profile were red, blue, white and yellow. These different colors were all possibilities for an individual to have and were also driven by a unique motivating force to keep them well grounded. For the people who has a red personality, Hartman said that they were driven by the force of power. Red personalities are usually dynamic and direct, assertive and very quick to make decisions. The concept of intimacy
Next, you will need to design sample mailings to submit to the USPS. The design must accommodate the barcode and it must be within a certain location. The barcode contains 31 digits that includes the unique id for the item, the Mailer id number, the mail class, and the routing zip. The mailer can choose to add additional information to the barcode including mailing campaign ID, customer ID and mailing number.
QR codes are similar to UPC barcodes that can be found on every item in the grocery store. The difference between UPC barcodes and QR codes are their storage capacity. QR codes can hold information in both ways the vertical and horizontal directions, while UPC barcodes only hold information only in one way the horizontal direction. This means that QR codes can contain more information than UPC barcodes. It is approximately 350 times more information.
RFID tags are much more efficient than simple barcodes because of a few key features. Unlike barcodes, RFID tags do not need to be on the surface of the object. This means that the tag does not need to be subject to the elements. RFID tags can also be read much more quickly than barcodes. Where barcodes need to have a device pointed directly at them to scan them, RFID tag readers need only be within range of the transmitting signal. This allows scanning process to be much more automated. Finally, RFID tags can be read almost simultaneously (mostly due to the high speed reading and use of different wave lengths) (What is RFID, n.d.).

DLP is the future of Home Cinema Quality projection. However, due to the high cost of manufacturing the chips, LCD and CRt are more viable options on the cost front. The potential drawback of this single-chip DLP technology is that in any given instant, the picture on the screen is not the total image, but is instead rapidly alternating between images consisting of the individual red, green, and blue colors. Thus the eye and the brain play the last critical role in making single chip DLP projectors work, by combining or averaging or integrating the picture, so that the viewer perceives the desired image and not the rapidly flashing momentary components of the image.
We see the number of vehicles around us in our daily life and everyone needs it but with the population increase, vehicles increased last decades in large quantity. But it created disturbances to the human life such as huge traffic, large sound, crime cases accidents, such as stealing of vehicles etc. and therefore we need management of vehicle. As a result, there is a lot of work going on to improve the transportation of vehicles. Out of these, Indian car plate recognition system is the most attractive research issue and this result manuscripts discusses some practical aspect of the recognizing number written on vehicle number plate. A Vehicle Plate Recognition System is a tracking system that identifies the vehicle so that the car is tracked down through our existing database. Each Number plates are unique for each vehicle, its takes the unique identification of each vehicle all over country. So its need to be monitor and recognize. We can track number plates in two ways firstly manually and second is automatically. In India traffic police noted manually the vehicle number plate. It is complex and not accurate reading. But automatic number plate recognition is the fast and efficient based system. Its helps to track the maximum number of system at a time with an accurate reading. Automatic number plate system uses the image

Barcoding is governed by Universal Product Code UPC whereas RFID is governed by electronic product codes EPC. In its evolution Barcodes were categorized as 1D, 2D and 3D with increasing capacity to store information like manufacturer, product type, batch number etc. Similarly RFID has Active and Passive tags that are being chosen according to the necessity and level of security. An Auto-ID system implementation to a warehouse or a facility takes into account strategic,
In this paper, new adjustment tone mapping technique is presented for displaying high dynamic range image on a low dynamic range device without any lose in image details and maintains contrast of the image. Instead of linearly scaling the luminance of all pixels or introduce local gamma correction with
For addressing these problems, few other techniques have been proposed which includes such as Radio frequency identification tag or RFID, encrypted bar codes (1D and 2D). Bar codes (1D) contain the linear lines of different width arranged parallel in different sequences depending upon the code associated with it. Similarly, 2D barcodes contain rectangles of different dimension arranged in matrix form and, each rectangle denotes a character. Thus, the combination of rectangles arrangement in 2D square matrix makes a unique code for identification. Information related to the product can be uploaded on a central server and coupled with the code given on product barcode. Therefore, information regarding any product can be accessed using code generated by scanning barcode. Similarly, they are very useful in product tracking in supply chain. The labels having barcode are easy to produce by simple printing on paper or polymeric film which can be attached or sewed to the fabric. For avoiding the
This could prove to be very beneficial as communications increase between Harley Davidson and their suppliers. In areas that barcode scanners have repeatedly failed, RFID technology would prove to be more accurate and efficient. The RFID tags can store data up to 2 KB whereas, the bar code has the ability to read just 10-12 digits.
