23. 56 of 169 GE HEALTHCARE DIRECTION 5198351 100 Rev 1 DiscovERY DICOM CONFORMANCE STATEMENT The early release product software had a JPEG encode routine that is called the BAD ENCODER for the following explanation In the BAD ENCODER produced SOS OxFFDA header the entropy coding table selector codes are 0x11 They should be 0x00 This mistake is the key that specifies the BAD ENCODER processing problems The BAD ENCODER computation of the pixel value difference to be entropy encoded is computed as Predictor value when it should be calculated as value Predictor 1 The result is that the decompression via industry standard packages result in a negative of the original image pixel value The BAD ENCODER predictor value used at the beginning of each line uses the last value of the previous line in the image The JPEG standard says the predictor for the first line element of each line should be the first element of the line immediately above the current line The first line first element predictor should be the unsigned value that is half the full scale range for the sample precision The first line first element predictor is correctly determined in the BAD ENCODER Explanation This section is provided to explain what was done during Image encoding so that people who wish and need to decode the images can modify the available JPEG codec software These packages are available from the WEB and were originally developed at Stanfor
