Title: Pattern recognition device and standard pattern generating method
Inventor: AMANO AKIO
IPC: G10L15/06
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a standard pattern which has a high recognition degree by measuring how much temporarily generated probability distributions by classes overlap with each other, and correcting distributions which overlap with each other and reducing their overlap. SOLUTION: As for the completed probability distributions of the respective classes, how much the classes overlap with each other is measured (302). Denoting the number of the classes to be recognized as N, (N2-N)/2 pairs are present, so overlaps of the distributions are measured as to all the pairs. When a measured value exceeds a previously set threshold value, it is considered that the distributions overlap large and the number of distributions exceeding the threshold value is counted and denoted as K (303). Then it is decided whether or not the count value K is larger than the previously set threshold value Kth (304) and when the K is larger than Kth, the process is finished, but when not, those probability distributions are selected as distributions to be corrected (305) and corrected (306).

Abstract: PURPOSE:To reduce memory capacity retaining a high compression speed by setting thinning memory with values which capacity of a frame memory is divided by the minimum compression ratio and giving the upper limit to the compression data amount as well as a line buffer size. CONSTITUTION:Raw picture data generated from an original scan part 1 are sent to a line buffer 2 and a thinning circuit 5 to store the data in a thinning memory 6. The memory 6 has functions of outputting from the data written previously in order and has value capacity obtained by dividing whole data amount of original picture for one copy of the original by the minimum compression ratio. A buffer 2 generates a prohibition signal LBFL of writing when there is no space for writing. A coder 3 compresses the raw picture data to store them in a buffer memory 4. A controller 7 decides whether the compression data amount in the memory 4 exceeds a prescribed amount or not.
