摘要： A process for X-ray registration and differencing results in more efficient compression. Differencing of registered modeled subject image with a modeled reference image forms a differenced image for compression with conventional compression algorithms. Obtention of a modeled reference image includes modeling a relatively unrelated standard reference image upon a three-dimensional model, which three-dimensional model is also used to model the subject image for obtaining the modeled subject image. The registration process of the modeled subject image and modeled reference image translationally correlates such modeled images for resulting correlation thereof in spatial and spectral dimensions. Prior to compression, a portion of the image falling outside a designated area of interest may be eliminated, for subsequent replenishment with a standard reference image. The compressed differenced image may be subsequently transmitted and/or stored, for subsequent decompression and addition to a standard reference image so as to form a reconstituted or approximated subject image at either a remote location and/or at a later moment in time. Overall effective compression ratios of 100:1 are possible for thoracic X-ray digital images.

摘要： A method for encoding compressed graphics video information and decoding such information. The method consists of enriching the video information in zeros through shifting and Exclusive ORing video image with itself. A number of methods are attempted in the shifting and Exclusive ORing process in order to determine the method which yields the optimum zero enriched image. The zero enriched image is then encoded and the encoded information stored. Upon retrieval, the information is decoded and an Exclusive OR and shifting process is done to obtain the original video information.

摘要： An image data compression transmission method performs coding of image data into coded data line by line, by a predetermined coding process, adding a synchronizing code to the coded data and generating coded information data by means of a coder. A decoder extracts the synchronizing code from the coded information data, and initializes a decoding process at the receiving side. The decoder determines the validity of the coded information data received from the coder based on the synchronizing code extracted therefrom.If the information data is invalid, then, the decoder performs error processing.

摘要： A system for recording received picture data for facsimile transmission includes a compressor for encoding decoded received picture data per line as a unit and compressing the encoded picture data to produce compressed data. A decision unit is connected to the compressor to decide whether the number of bits of the compressed picture data or the number of bits of the restored picture data is smaller to produce a control signal representing the decision result. A buffer storage unit is operatively connected to the compressor for storing the picture data having a smaller number of bits decided by the the decision unit. The system also includes an output decoder connected to the buffer unit for delivering a decoded original picture data in the buffer storage when the data from the buffer storage is compressed data and delivering the data from the buffer storage unit when the data from the buffer storage unit is original picture data.

摘要： A method of diagnosing the operating conditions of an image processor comprising the steps of preparing a first pattern of data, a second pattern corresponding to the first pattern when it has been compressed normally, a third pattern of data, and a fourth pattern corresponding to the third pattern when it has been expanded normally; diagnosing an operating condition of the compressor by comparing data after the first pattern has been compressed by the compressor with the second pattern; and diagnosing an operating condition of the expander by comparing data obtained after the third pattern has been expanded by the expander with the fourth pattern. The independent diagnosis of the compressor and the expander allows the specific defective chip of component to be identified, thereby facilitating proper repair.

摘要： An image processing system for selecting a set of predictors based on characteristics of the data to be compressed. The image processing system includes a predictor stage, having a multiple predictors, in which input image data is conditioned by a predictor as selected from among a set of predictors according to the number of prediction errors. The set of predictors is selected according to a bit pattern of the input image data. The conditioned data is compressed and transmitted to a decompressor where it is decompressed, depredicted, and output in the form of an image. The data compressing system includes circuitry for determining whether input image data is gradation data or text image data, circuitry for applying a boundary code to the image data when the determining means detects a change point where the image data is changed from the text image to the gradation data or from the gradation data to the text data, and a compressor including boundary code detecting circuitry and two predictor sets respectively for the gradation image data and the text image data after detecting a boundary code, the compressor selects the predictor set most suitable for the input image data.

摘要： A data compression system is provided having a fixed length coding unit provided before a universal coding unit. The fixed length coding unit detects mode classifications and mode conditions of changing picture elements in a mode detecting unit. Then, the mode classifications and mode conditions are converted to fixed length code words in a code transforming unit representative of, e.g., MH, MR or MMR-type codes. Thereafter, the fixed length code words are predictively coded by the universal coding unit to output compressed data. The present invention is applicable to both character data and picture data. Preferably, the picture data is preprocessed by the fixed length coding unit before both of the character data and picture data are predictively coded by the universal coding unit.

摘要： An electrophotographic copying apparatus, which is able to classify an image in a copy area of the original. The electrophotographic copying apparatus estimates a copy area of an original within a scan area based on copy condition data set and stored through an operation unit. A sampler samples the scanned image data in the copy area to form image data. An identifying unit uses the image data thus obtained to identify an image classification of the copy area from a group of image patterns.
