Abstract

The invention discloses an information processing method and an electronic device. A first image for an operation object is acquired, and the first image includes M pixel points; and the M pixel points of the first image are determined The detection parameter value corresponding to each pixel point, the detection parameter value is the difference value between the pixel point and the standard value; according to the detection parameter value, N pixels that meet the first condition are selected from the M pixel points The target pixel; the first condition is that the detection parameter value corresponding to the pixel is greater than the first threshold; M is a positive integer greater than 1, and N is an integer less than or equal to M and greater than or equal to 0; extracting the N target pixels feature information.

Description

technical field [0001] The present invention relates to information processing technology, in particular to an information processing method and electronic equipment. Background technique [0002] With the development of fingerprint identification technology, integrated fingerprint identification on handheld devices is gradually accepted by consumers. At present, traditional fingerprint recognition algorithms such as line correlation detection method, thinning skeleton method and gradient direction detection method all have the problem of large amount of calculation in the process of extracting fingerprint details. Therefore, due to the limitations of factors such as power consumption and computational complexity, the traditional fingerprint recognition algorithm still cannot meet the real-time processing requirements in the current embedded environment. Contents of the invention [0003] In view of this, the embodiments of the present invention provide an information pro...
