Abstract

The invention discloses a simplified method of an image convolution response value, aiming at the problem that the calculation amount of calculating the image convolution response value in the prior art is large. The simplified method of the image convolution response value comprises the following steps: firstly, obtaining an integral video of a video image based on gray level information and motion information of each pixel in the video image; then, using a box filter to simplify the convolution operation of point multiplication into addition and subtraction operation, thus greatly simplifying the response value; then, calculating and obtaining the response value of each cubic unit in the box filter by means of the element response results at preset positions of each cubic unit in the boxfilter; and finally, performing addition and subtraction operations by means of the response value of each cubic unit in the box filter to obtain the video image response value. The simplified methodof the image convolution response value provided by the invention simplifies the calculation method of the video image response value with a huge amount of calculation in the prior art to a calculation method of obtaining the video image response value by means of the calculation result calculated by simply using the box filter composed of cube units and the video image.

Description

technical field [0001] The present invention relates to the technical field of video processing, and more specifically, relates to a method for simplifying image convolution response values. Background technique [0002] It can be understood that by determining the spatio-temporal feature points in the video and describing them, the characterization of the video can be realized in two-dimensional space and time, and when determining the spatio-temporal feature points in the video, it is necessary to calculate the pixels in the three-dimensional video image The response value of the response value and then determine the spatio-temporal feature points, but the calculation of the response value is a convolution operation in three dimensions of time dimension and two-dimensional space dimension. The calculation amount of the "three-dimensional" convolution operation is very large. A simplified method of image convolution response value, and simplifying the calculation of respons...
