METHOD, APPARATUS AND TERMINAL FOR DETECTING IMAGE STABILITY

摘要

An apparatus and terminal perform a method for detecting image stability in image processing. The method includes: acquiring N consecutive image frames, wherein N is an integer equal to 2 or larger; performing in each of the N consecutive image frames, the following: detecting corner points in the image frame, dividing the image frame into multiple areas, and recording distribution of the corner points in each of the multiple areas of the image frame in order to obtain a description vector of the image frame; calculating a number of areas according to the description vector of the image frame over the N consecutive image frames, wherein an existing state of the corner points has changed; determining whether the N consecutive image frames are stable, based on the number of areas which the existing state of the corner points has changed over the N consecutive image frames.

1. A method for detecting image stability, comprising:
acquiring N consecutive image frames, wherein N is an integer equal to 2 or larger; performing in each of the N consecutive image frames, the following:
detecting corner points in the image frame,dividing the image frame into multiple areas, andrecording distribution of the corner points in each of the multiple areas of the image frame in order to obtain a description vector of the image frame;calculating a number of areas according to the description vector of the image frame over the N consecutive image frames, wherein an existing state of the corner points has changed; determining whether the N consecutive image frames are stable, based on the number of areas which the existing state of the corner points has changed over the N consecutive image frames.
