Abstract: A method of and a system for finding similarities between major boundaries of images using a wavelet detector is described herein. Unimportant edges of the image are disregarded by eliminating Gaussian wavelet coefficients and Haar wavelet coefficients of lower significance. Comparison between the images is made on the basis of quantized color, sign and magnitude of the Haar wavelet coefficients. The method performs the comparison between images in two steps. First, the method checks for exact matches between the Haar wavelet coefficients to determine whether the images are very similar. This is followed by binning of the coefficients into nine spatial bins in the image. A representative is assigned to each of the bins in terms of color, orientation and sign. Each bin of one image is compared with all the bins of the other image. Thus, images that are similar but not identical are still detected.

Abstract: Compression of a video by segmentation, transformation, transform encoding, difference encoding, and muxing. The segmentation looks at energies of the frames, in order to find three different things: black frames which have energy less than the specified amount, consecutive frames which have energy difference is less than the specified amount, and changes in scene which have energy difference is more than a specified amount. If there is little or no energy or energy difference, then the frame is replaced by an indication rather than information about the frame itself; either an indication of a black frames or an indication of no change between two adjacent frames. If there is much energy, then this is taken as the beginning of a new scene, and used as an area to change group of frames.

Abstract: A technique for selecting portions of a multi-resolution medical image data set to be stored and the portions of the multi-resolution medical image data set to be discarded in order to reduce the overall amount of image data that is stored for each image data set. The selection is based on the clinical purpose for obtaining the medical image data. The clinical purpose for obtaining the medical image is used to define regions of interest in the medical image. At each resolution level of the multi-resolution medical image data set, the regions of interest are stored at the full resolution, while the remaining portions of the medical image are stored at a lesser resolution. A three-dimensional bit mask of the regions of interest is produced from a segmentation of the regions of interest. The segmentation list and the multi-resolution medical image data set are decomposed into multiple resolution levels. Each resolution level has a low frequency component and several high frequency components.

Abstract: In this invention, even if final code data is to be generated by selectively discarding code data for each bitplane, errors due to bitplane rounding down operation can be suppressed from being gradually accumulated in predicted data such as P- and B-pictures, thereby preventing a deterioration in image quality. For this purpose, a block segmentation unit (31) segments an input frame into a plurality of blocks, and supplies the respective blocks to a difference computing unit (32). The difference computing unit (32) outputs the blocks to a DWT unit (33) without any change when the intra-frame coding mode is set. When the inter-frame coding mode is set, the difference computing unit (32) outputs the result obtained by computing a difference from predicted data from a motion compensation unit (42) to the DWT unit (33).

Abstract: A video coding system and method utilizes a 3-D wavelet transform that is memory efficient and reduces boundary effect across frame boundaries. The transform employs a lifting-based scheme and buffers wavelet coefficients at intermediate lifting steps towards the end of one GOP (group of pictures) until intermediate coefficients from the beginning of the next GOP are available. The wavelet transform scheme does not physically break the video sequence into GOPs, but processes the sequence without intermission. In this manner, the system simulates an infinite wavelet transformation across frame boundaries and the boundary effect is significantly reduced or essentially eliminated. Moreover, the buffering is very small and the scheme can be used to implement other decomposition structures. The wavelet transform scheme provides superb video playback quality with little or no boundary effects.

Abstract: The invention relates to a method of selecting among N “Spatial Video CODECs” where N is an integer number greater than 1, the optimum “Spatial Video CODEC” for a same input signal I. “Spatial Video CODEC” is understood as the combination of any transform of the input signal, followed by a quantization of the transform coefficients and a corresponding entropic coder. Firstly from all the N “Spatial Video CODECs” for the same input signal I and a same quality parameter Q, the rate R and the distortion measures D are obtained.

The optimality criterion is defined as the minimization of the value Ln=f(Rn,Dn) calculated for all the n from 1 to N. n is the index of the “Spatial Video CODEC”, where f(Rn,Dn) is a function of Rn and Dn.

The output of the first coding chain may be stored in memory in a file structure that can be accessed independently of the second chain's output and, therefore, it facilitates real time decoding and playback.

Abstract: An in-camera two-stage compression implementation is described that reduces the latency between snapshots to a fraction of that otherwise required by other systems that either process complete compression following each snapshot or that incorporate heavy, bulky, and expensive RAM hardware capable of maintaining several raw luminosity records (unprocessed file containing a digital image). In the 1st stage compression the raw luminosity record is quickly, yet partially, compressed to available RAM buffer space to allow a user to expeditiously capture a succeeding image. When the higher-priority processes, the user shooting pictures, and stage one compression subside, a 2nd stage compression, which is slower but more effective, decompresses the earlier partially-compressed images, and re-compresses them for saving in flash memory until they are distributed to a remote platform to be finally converted to the JPEG2000 format.

Abstract: Exemplary improvements for in-band wavelet video coding with spatial scalability are described. In one implementation an encoder uses leaky prediction to balance a trade-off between reducing drifting errors at lower resolutions while maintaining coding performance at higher resolutions. In an alternative implementation, a trade-off technique defines two coding modes at the macroblock level. The first mode includes predictions employed at a low quality reference while the second mode includes predictions employed at a high quality reference. The method then adaptively selects the proper coding mode for each macroblock according to a rate-distortion criterion.

Abstract: Image data to be compressed is first converted from the RGB domain into a gamma-powered YUV domain. A wavelet transform then separates image data into high- and low-detail sectors, incorporating a dynamic scaling method, allowing for optimal resolution. The output data from the wavelet transform is then quantized according to an entropy-prediction algorithm that tightly controls the final size of the processed image. An adaptive Golomb engine compresses the data using an adaptive form of Golomb encoding in which mean values are variable across the data. Using variable mean values reduces the deleterious effects found in conventional Golomb encoding in which localized regions of similar data are inefficiently coded if their bit values are uncommon in the data as a whole. Inverse functions are applied to uncompress the image, and a fractal dithering engine can additionally be applied to display an image on a display of lower color depth.
