摘要： A technique for processing a digital image is provided. According to an embodiment, the technique comprises providing the digital image in a compressed format, wherein the digital image is represented as a bitstream representing sequential image blocks (12), each block comprising one or more components (14), each component comprising several data units and each data unit being represented as a Huffman-coded stream of coefficients of basis functions (16), wherein a zeroth order coefficient is represented as a difference to the previous zeroth order coefficient of the corresponding component. The technique further comprises processing the digital image using a processing unit by sequentially stepping through the bitstream. While stepping through the bitstream, the technique comprises storing in a block information table (18) an indicator to one zeroth order or first order coefficient of each image block in the bitstream and decoding the zeroth order coefficients and storing in the block information table the zeroth order coefficient of the first data unit of each component of each image block, said zeroth order coefficient being represented in a non-differential form. Said stepping through non-zeroth order coefficients of a data unit in the bitstream, said non-zeroth order coefficients being represented by a sequence of bitstream entries, comprises looking at a bit sequence (20) of a predetermined number of following bits in the bitstream, making a table lookup (22) to determine category and zero run length of at least the first bitstream entry in the bit sequence and to determine the bit length of the first bitstream entry, skipping (24) the number of bits in the bitstream corresponding to the determined bit length, summing (26) the number of skipped bits for gathering information regarding the number of bits in the bitstream between coefficients of zeroth or first order in adjacent data units; and summing (28) the number of coefficients having been stepped through until all coefficients of the data unit have been stepped through or an end of block symbol is encountered.

摘要： According to an aspect of an embodiment, a method of character recognition out of an image having a frame and a plurality of characters in an area, comprises the steps of: dividing the area into a plurality of partial areas having a plurality of partial images, respectively; providing a template image having a reference frame image; calculating differences between the partial images and the reference frame image of the template image, respectively; calculating misalignment of the image from the template image based on the average of the differences of the partial images and the reference frame image; and recognizing the characters out of the image upon correction of the misalignment.

摘要： A method of generating a binary Sel plane for image compression is disclosed. The method first generates a 2 bit gray selector (GraySel). This 2 bit selector is then processed in a second stage to produce a binary Sel decision which minimizes the compression noise evident in the reconstructed image. The method used here to generate the 2 bit GraySel applies a set of prioritized rules over a small 3x3 window that is well suited for segmenting synthetic, PDL generated images that are typically free of scanner noise. The method not only marks the proper sense of the selector when it is known, but also include a 3 rd state that indicates that the selector decision is weak or unknown. This weak decision can then be optimized in the second stage process based on strong edges information in the neighborhood.
