Title: Image encoding device, image decoding device and their methods
Inventor: FUKUHARA TAKAHIRO
IPC: H04N19/60
Filed: 1998-03-22
Abstract: PROBLEM TO BE SOLVED: To obtain encoded and decoded images of high image quality with low block distortion even in high compressibility by dividing an orthogonal transformation coefficient into plural pieces of zones whose statistical qualities are different and separately encoding a coefficient in each zone. SOLUTION: An orthogonal transforming part 1 performs discrete cosine transformation (two-dimensional DCT) of input image data D100 and obtains orthogonal transformation coefficient data D101. A quantizing part 2 quantizes the orthogonal transformation coefficient to be inputted and produces quantization coefficient data D102. A zone division type scanning part 3 divides a quantization coefficient group to be inputted into plural zones by utilizing that correlation exists in the relation of a characteristic belonging to an image and the position of the orthogonal transformation coefficient and outputs a scan output D103 collected in each divided zone. An entropy encoding part 4 outputs coefficient data D104 that are subjected to Huffman coding in each zone as a bit stream to a transmission system. A decoding part inversely transforms received data in a reverse order and restores the image data.

Abstract: PROBLEM TO BE SOLVED: To segment a character area where the direction of characters is different in the same line with high accuracy and to improve recognition precision with respect to a vertical original like a horizontal writing numeric character in a vertical writing line. SOLUTION: A line is segmented (2), a character is segmented (3), recognition processing (4) and post-processing (5) are performed, and a reliability calculating part 6 calculates the probability of a recognition result.

When character height after segmentation is almost equal to precedent character height, it is decided that rerecognition processing is needed (9). The reliability of a 1st recognition result is compared with the reliability of a 2nd recognition result (10), and the recognition result that has the higher reliability is outputted (11).
