Document Type and Number:
Japanese Patent JP6835407
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an image processor, an image processing method and a program capable of calculating similarity of different images with high accuracy.SOLUTION: An image processor 100 is provided with: a data acceptance part 10; a feature quantity calculation part 12; an individual similarity calculation part 14; a weight setting part 16; and a total similarity calculation part 18. The feature quantity calculation part 12 calculates local feature point density and a local feature quantity, and calculates one or more kinds of feature quantities except a local feature point from image data on a query image input in the data acceptance part 10. The individual similarity calculation part 14 calculates individual similarity between the query image and each of a plurality of dictionary images for every feature quantity. The weight setting part 16 sets weight of each feature quantity based on the local feature point density of the query image. The total similarity calculation part 18 calculates the total similarity between the query image and each of the plurality of dictionary images based on the individual similarity for every feature quantity and the weight of each feature quantity.SELECTED DRAWING: Figure 1
