Abstract

The present application provides a ROI template generation method, a ROI extraction method, a system, an apparatus, and a medium. Wherein the ROI region extraction method includes identifying an organregion in the obtained face image; the preset ROI region template is adjusted to the edge of the recognized organ region to obtain the ROI region of the face image. The present application solves theproblem in the prior art that the area data processed in the face image processing using the ROI area template is not accurate enough.

Description

technical field [0001] The present application relates to a facial image processing technology, in particular to a method for generating an ROI template, a method for extracting an ROI, a system, a device, and a medium. Background technique [0002] The ROI region (region of interest) is the area to be processed that is outlined in the form of a box, circle, ellipse, irregular polygon, etc. from the processed image in machine vision and image processing. In the field of image processing, a region of interest (ROI) is an image region selected from an image. This region can be used as the focus of image analysis and delineated for further processing. Using ROI regions can reduce processing time and increase accuracy. [0003] In facial image processing technology, technicians use multiple facial sample images for machine learning to obtain facial ROI areas, and use the obtained ROI areas for beauty, special effects, pathological analysis, and facial evaluation. Because the r...
