Abstract

The embodiment of the invention provides a method for detection of a specific object region in an image, which comprises: Extraction Step: extracting common object features from the image, and detecting the extracted common object features by a detector which is obtained via sample training and corresponds to verification attributes so as to obtain candidate frames of a specific object in compliance with the verification attributes in the image; and Verification Step: verifying all the obtained candidate frames to judge whether the candidate frames contain the specific object or not according to the verification attributes and special features of the specific object, wherein the candidate frame containing the specific object is judged to be a specific object region. The embodiment of the invention also correspondingly provides a device for detection of the specific object region in the image.

Description

technical field [0001] The present invention relates to a method and a device for detecting a specific object area in an image, and more particularly, the present invention relates to a method and a device for detecting a specific object area by using specific features of a specific object. Background technique [0002] With the development and wide application of computer image processing technology, the demand for object detection technology is also increasing day by day, such as human faces, pedestrians, vehicles and so on. Face detection, pedestrian detection, and vehicle detection have become basic problems in the field of computer vision and pattern recognition. The above technologies can be used for obstacle detection, scene recognition, and website image classification. Among them, vehicle detection is a necessary technology for intelligent traffic monitoring, driver assistance systems, and automatic driving. Currently, research work focuses on this field and propose...
