Problems solved by technology

[0003] The current method of detecting the region of interest usually uses a large number of training samples of the region of interest image to train the neural network, and uses the trained neural network to detect the region of interest in the image. This method has low detection efficiency. It takes a long time and it is difficult to meet the requirements of real-time detection

Abstract

This application relates to the technical field of information processing, and discloses a detection method, device, electronic equipment, and readable storage medium for a region of interest. The detection method for a region of interest includes: acquiring a target video frame image, and dividing the target video frame image into A plurality of image blocks of preset size; for each image block, the chrominance component of each pixel point of the image block is obtained, and the qualified point ratio of the image block is determined according to the chrominance component of each pixel point; the qualified point ratio is the The ratio of pixels meeting the preset chromaticity conditions in each pixel of the image block; based on the qualified point ratio of each image block, determine the area type of each image block; generate the region of interest map according to the area type of each image block, based on The region of interest map detects the region of interest in the image of the target video frame. The detection method for the region of interest provided by the present application has high detection efficiency and short time consumption, and can meet the requirements of real-time detection.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, the present application relates to a detection method, device, electronic equipment and readable storage medium for a region of interest. Background technique [0002] A region of interest (ROI) is a region to be processed that is outlined in a box, circle, ellipse, irregular polygon, etc. from the processed image in machine vision and image processing. When processing an image, the region of interest in the image is detected first, which can reduce the processing time of the image and increase the accuracy. [0003] The current method of detecting the region of interest usually uses a large number of training samples of the region of interest image to train the neural network, and uses the trained neural network to detect the region of interest in the image. This method has low detection efficiency. It takes a long time and is not easy to meet the requireme...
