Title:
IMAGE PROCESSING METHOD AND APPARATUS, AND COMPUTER DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/151153
Kind Code:
A1
Abstract:
An image processing method and apparatus, and a computer device and a storage medium, by which a pixel value calculation result of a finally obtained feature map having a fixed size is relatively accurate. The method section comprises: obtaining a candidate region feature map; dividing the candidate region feature map into NxM small regions having the same size according to preset candidate region pooling parameters; averagely dividing each small region into P sampling regions according to a preset sampling point number P; determining intersected pixel points intersected with each sampling region in the candidate region feature map (S40); determining a pixel value of a central point position of the sampling region according to the intersected pixel points; correspondingly determining the pixel value of each small region according to the pixel value of the central point position of each sampling region corresponding to the small region (S60); and obtaining the candidate region feature map having a fixed size according to the pixel value of each small region (S70).
