Title: Picture recognizing method
Inventor: TOKITA NAOYUKI
IPC: G06K9/38
Filed: 1985-08-01
Abstract: PURPOSE:To prevent the misdiscrimination of a picture containing plural stamped characters which is due to the variable density of stamping ink, by recognizing the picture to be discriminated based on a slice level where the number of binary-coded picture elements in a specific area is approximately equal to the number of reference picture elements. CONSTITUTION:Multi-value coded signals of a reference picture are stored in a storage part 22 and about the middle level of the stored signal is defined as a reference slice level out of many stage levels. Thus the number of reference picture elements is decided for each character and the area of an optional character in the picture 11 is defined as a specific area 12. Then multi-gradation signals in a picture 11a to be discriminated are stored in a storage part 22 and then binary-coded at a signal processing part 23 based on the reference slice level to obtain the number of picture elements of the characters in a specific area 12a corresponding to the area 12. This number of picture element is compared with the corresponding number of the reference picture elements. Based on the result of this comparison, the slice level to the multi-gradation signal is set higher or lower than the reference slice level by a stage. This action is repeated to obtain the approximate coincidence with the number of picture elements in the area 12 for execution of recognition of pictures.
