Target image determination method and system, computer device, and computer storage medium

Abstract

The present invention relates to a target image determination method and system, a computer device, and a computer storage medium. The target image determination method comprises the following steps:S10, calculating hue characteristic parameters, saturation characteristic parameters and luminance characteristic parameters corresponding to each pixel point according to the RGB values of each pixelpoint in the original image; S20, calculating an amplitude spectrum and a phase spectrum of the original image according to the hue characteristic parameter, the saturation characteristic parameter and the luminance characteristic parameter, and calculating an image feature description spectrum of the original image according to the amplitude spectrum; S30, inverse Fourier transform of that characteristic description spectrum and the phase spectrum of the image to determine a characteristic image; S40, superimposing the feature image and the original image, and determining a target image according to the superimposed image data. The method and the system for determining the target image provided by the invention enable the determined target image to include more effective image data on the original image, thereby facilitating the stability of the target image in the subsequent detection and analysis process.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and system for determining a target image, computer equipment, and a computer storage medium. Background technique [0002] Image processing technologies such as face detection are currently one of the research directions that have received widespread attention. For example, the face detection technology can be applied to many aspects such as the daily passenger flow of the subway. How to determine the target image for specific detection (such as the face image that needs to be finally recognized) from a large amount of image data is the most important thing in the research of this technology. [0003] Traditional schemes generally directly extract the image data obtained by shooting and other methods as the target image for corresponding detection and analysis, and the target image determined in this way may easily affect its stability in the subsequent...
