| 20080205782 | JPEG Processing Engine for Low Profile Systems - A method is provided for processing minimum coded units (MCUs) in a Joint Photographic Expert Group (JPEG) bit stream representing an image. A data structure is generated for storing MCU block numbers, corresponding MCU block coordinates, and corresponding MCU block editing lists. When an editing operation to the image is received, the editing operation is saved to a group of the MCU block editing lists of a group of the MCUs affected by the editing operation. Later the MCUs are retrieved from the JPEG bit stream one at a time and then processed according to the editing operations in the corresponding MCU blocking editing lists. | 08-28-2008 |
| 20080260275 | Image Coding Apparatus - An image coding apparatus includes a rate control information extraction means for determining which up to a coding pass in which code block should be coded from the sum of the code amounts of the code blocks, the slope of an RD curve calculated from the distortion difference between a coding distortion at a time of coding each coding pass and a coding distortion at a time of coding a preceding coding pass, and the number of output bytes of the code amount of each coding pass, and the inverse of one of given rate control parameters which are listed in order of decreasing monotonously, and for outputting an end-of-coding pass, and a coded data extraction means for reading coded data including up to coded data corresponding to the end-of-coding pass, for adding the number of coding passes to the coded data, and for outputting them as a code stream. | 10-23-2008 |
| 20080260276 | Data Compression-Decompression Method, Program, and Electronic Device - An electronic device includes: a PHLCT circuit ( | 10-23-2008 |
| 20080310747 | SOFTWARE FOR CREATING ENGRAVED IMAGES - A method of producing an engraved image on a computer screen includes loading an image to be engraved and converting the image into a high contrast image using at least two colors. The first lighter color is used for the lighter portions of the high contrast image and a darker color is used for the darker portions of the high contrast image. Mixing of the colors is based on the luminance level of the image. A plurality of lines are drawn over the high contrast image with variations in the plurality of lines drawn being a function of the luminance of the underlying image. | 12-18-2008 |
| 20090046940 | EMBEDDED MESSAGES IN PICTURES - The present invention relates to a system and method for indicating the presence of ancillary data in a header of a JPEG file. The system comprises a JPEG file having an EXIF header and associated image data, and at least one other file of digital data, and a computer. The computer is programmed to scan the JPEG image file for a special indicator in the application marker section of the EXIF header. If the marker is present, the value of marker indicates what type of ancillary digital data is present in the header. For instance, if the marker contains the string EKC-JPEG, then the ancillary data is known to be another JPEG file. Other types of data can be indicated as appropriate. The presence of the ancillary data is then used for the appropriate type of presentation to the user. A reveal icon is then used in presenting the data to indicate whether the ancillary data is another JPEG file, video, audio, sound, document, etc. The user would be presented with the data as appropriate. | 02-19-2009 |
| 20090097769 | SYSTEMS AND METHODS FOR SECURELY PROCESSING FORM DATA - A form image may be split into a plurality of image fragments. Each image fragment may correspond to a field of the form. Each form fragment may be deidentified to prevent unauthorized reconstruction of the form image from its respective image fragments. An index to associate each image fragment to its respective form and form field may be generated. Form fragments from a plurality of form images may be intermixed in an image fragment pool and selected for transmission to a third-party form processor. The third-party form processor may be an internal third-party form processor or an external, third-party form processor. The third-party form processor may assign a data value to each image fragments, associate each data value with a name corresponding to, or derived from the form image fragment name, and return the data values. The data values may be stored and associated with their respective forms and/or form fields using the index. | 04-16-2009 |
| 20090220163 | METHOD AND SYSTEM FOR DECODING ENCODED IMAGES AND REDUCING THE SIZE OF SAID IMAGES - A method and system for reducing the number of mathematical operations required in the JPEG decoding process without substantially impacting the quality of the image displayed is disclosed. Embodiments provide an efficient JPEG decoding process for the purposes of displaying an image on a display smaller than the source image, for example, the screen of a handheld device. According to one aspect of the invention, this is accomplished by reducing the amount of processing required for dequantization and inverse DCT (IDCT) by effectively reducing the size of the image in the quantized, DCT domain prior to dequantization and IDCT. This can be done, for example, by discarding unnecessary DCT index rows and columns prior to dequantization and IDCT. In one embodiment, columns from the right, and rows from the bottom are discarded such that only the top left portion of the block of quantized, and DCT coefficients are processed. | 09-03-2009 |
| 20090220164 | IMAGE PROCESSING APPARATUS AND COMPUTER READABLE MEDIUM - An image processing apparatus includes: an image accepting unit that accepts an image; a pixel addition unit that specifies a reference pixel for reference based a demarcation, with each area of object within the image accepted by the image accepting unit or each sub-area into which the area is divided as the demarcation, and that adds a pixel at a position independent from a cluster of pixels within the image on the basis of the reference pixel; and an output unit that outputs the image to which the pixel is added by the pixel addition unit. | 09-03-2009 |
| 20090263034 | System and Method For Signal Processing Using Fractal Dimension Analysis - A system and method of signal processing using linear or non-linear signal transformation and fractal dimension based analysis. Using a transform process (i.e. wavelet transform, Fourier transform, ICA transform, etc.), a signal is decomposed into a series of coefficients or components. Within this transform domain, fractal dimensions of the components are computed. The components with fractal dimensions higher than a pre-determined threshold are then selectively processed. A modified signal is reconstructed using inverse transform of the signal components. | 10-22-2009 |
| 20090297055 | SUPERVISED EDGE DETECTION USING FRACTAL SIGNATURES - Methods and systems to identify image pixels as edge pixels using fractal signatures associated with the image pixels. Fractal signatures may include one or more of a variety of fractal dimensions. A fractal dimension of a pixel may be generated from an array of pixels that include the pixel, from x and y coordinates and one or more of luminosity values and color values associated with pixels in the array of pixels. Pixels may be identified as edge pixels when their corresponding fractal signatures are equal to or greater than a fractal signature threshold. The fractal signature threshold may be generated in a supervised fashion. | 12-03-2009 |
