The purpose of the DCCS is to give Producers an efficient mechanism to track, validate and authenticate their goods and services as they travel through the supply chain. The attributes for the data to be coded are defined real time and are virtually unlimited. Once the attributes are defined the data is entered using alphanumeric, characters or images into the system and processed through the encoder. The encoder is uses MDCT and Vector Quantization technology, along with the Mobis function. While the data is being processed through the encoder a time stamp and reference number is embedded into the code for authentication. Once encoded a label is created with the color code, the vector of the code and the color space vector. The application can create the code in many shapes that include honeycomb, squares, circles, PDF417 Barcode.

The determination of specific transcoding parameters, used for transcoding multimedia content, can be performed by utilizing the results of content analysis of the multimedia content. One of the results of the content analysis is the determination of image type of any images included in the multimedia content. The content analysis uses one or more of several techniques, including analyzing content metadata, examining colors of contiguous pixels in the content, using histogram analysis, using compression distortion analysis, analyzing image edges, or examining user provided inputs. Transcoding the multimedia content can include adapting the content to the constraints in delivery and display, processing and storage of user computing devices. | 05-19-2016 |
20160148067 | METHOD AND SYSTEM FOR CLASSIFYING IMAGE ELEMENTS - A method, system, and machine-readable medium for classifying an image element as one of a plurality of categories, including assigning the image element based on a ratio between an unoccluded perimeter of the image element and an occluded perimeter of the image element and coding the image element according to a coding scheme associated with the category to which the image element is classified. Exemplary applications include image compression, where categories include image foreground and background layers. | 05-26-2016 |
20160148385 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND NON-TRANSITORY STORAGE MEDIUM STORING IMAGE PROCESSING PROGRAM - A similarity calculation unit calculates a similarity between pixel values of a target pixel and a reference pixel and a similarity between the pixel value of the target pixel and an average value of pixel values of reference pixels, in an input image. A weighting factor calculation unit calculates weighting factors based on the calculated similarities. A weighted average value calculation unit calculates weighted average values of the pixel value of the reference pixel and the average value of the pixel values of the reference pixels by use of the calculated weighting factors. A subtraction unit calculates a difference value between the pixel values of the target pixel and the reference pixel. An isolation degree calculation unit calculates an isolation degree based on the calculated deference value. A correction unit corrects the target pixel based on the calculated isolation degree. | 05-26-2016 |
