Problems solved by technology

Therefore, the number of feature points depends on the design of the screen, and therefore, it is impossible to control the number of feature points so that the required number of feature points remains
Furthermore, it is impossible to remove feature points in a spatially uniform manner

Abstract

There is provided an image processing device including a feature point detection unit configured to detect feature points from an image, a reliability computation unit configured to compute reliability of each of the detected feature points, and a removal processing unit configured to remove some of the detected feature points on the basis of the reliability so that the number of the remaining feature points in each split region that is obtained by splitting the image into a plurality of regions is within a restricted number of feature points.

Description

technical field [0001] The present technology relates to an image processing device, an image processing method, and a program. More specifically, the technique involves removing some feature points detected from an image in a spatially uniform manner. Background technique [0002] Conventionally, in various cases such as when searching for an object from an image, when detecting a moving object from an image sequence, or when performing alignment of multiple images, it is necessary to match the same object between multiple images. [0003] As a method of matching identical objects, a method called block matching or a method based on feature points is employed. [0004] In block matching, a given image is segmented into block regions, and SAD (Sum of Absolute Differences) or NCC (Normalized Cross-Correlation) is calculated. Then, according to the calculated SAD or NCC, a region with high similarity to each block is searched from another image. This method involves a rathe...
