Abstract

An embodiment of the invention discloses an image detection method and device. The method includes: utilizing a detection frame classifying model, and acquiring a target object detection frame having highest probability of belong to a target object in a to-be-detected image, wherein the detection frame classifying model is acquired in advance by training according to a first-type sample image labeling the target object; extracting image features in the target object detection frame; according to the image features of the target object detection frame, utilizing a target object classifier to detect whether the target object detection frame is the target object or not, wherein the target object classifier is acquired by training according to a primary sample of the target object and a secondary sample of the same in a second-type sample image. By the image detection method and device, effective detection of the to-be-detected image is realized, and image detection accuracy is improved.

Description

Technical field [0001] This application belongs to the field of image processing technology, and specifically relates to an image detection method and device. Background technique [0002] When the image has a complex background, how to detect the target object from the background of the image is a problem often encountered in the image processing process. Especially when the target object is a human body, it is involved in different technical applications. [0003] In the prior art, taking the detection of a human body in an image as an example, most of the image detection process is generally: first construct artificially designed rules or image features (such as human contour features, human body area histogram features, human body key point features, etc. ), and then train the detection model or classification model, and finally locate the position of the human body in the image through the obtained detector or classifier. [0004] However, with this existing image detection so...
