Problems solved by technology

Therefore, for images with different resolutions, if they are all equally expressed by the same level of features, this will make the images with different resolutions unable to have the same feature representation, so that these features cannot express each image well. The information actually contained in it leads to the low definition of the features extracted from it, which affects the recognition accuracy of the final facial attribute recognition and facial recognition

Abstract

The invention discloses an image processing apparatus and method, and a storage medium. The image processing apparatus includes: a unit that acquires more than one facial image of one person, whereinthe facial images have different resolutions; a unit that merges the first features obtained from the face images, wherein the first features for mutual merging have the same feature expression; and aunit for generating a second feature on the basis of the combined features. No matter what resolution exists between images from which features are to be obtained, especially for images with low resolution, clearer features can be obtained from the images.

Description

technical field [0001] The present invention relates to image processing, and more particularly to, for example, feature extraction processing and recognition processing. Background technique [0002] At present, monitoring systems usually use facial attribute recognition technology and / or facial recognition technology (for example, face matching, face search, etc.) to monitor a certain place. Generally, the monitoring effect of a monitoring system depends on the recognition accuracy of facial attribute recognition and facial recognition, and the recognition accuracy of facial attribute recognition and facial recognition depends on the useful information for recognition contained in the image used for recognition (for example, the information that can be obtained from it) clear facial features). In a monitoring system, especially in a wide-area monitoring system, devices (eg, cameras, video cameras, etc.) used to capture images usually capture various images, eg, images wit...
