Abstract

The embodiment of the invention discloses a method of detecting an image edge and a mobile terminal. The method comprises the steps of obtaining a password image entered by a user, converting the password image into a bianry image, searching a coordinate of an initial point of the edge of a target area in the bianry image, calculating with an edge tracing algorithm according to the coordinate of the initial point, obtaining edge information of the target area, and verifying the password image according to the edge information, wherein the edge tracing algorithm comprises an eight neighborhood based edge tracing algorithm based. With the adoption of the method and the mobile terminal, the edge information of the password image can be extracted simply and effectively to verify the password image.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for detecting an image edge and a mobile terminal. Background technique [0002] As mobile terminals such as mobile phones and tablet computers become more and more powerful and widely used, the security of mobile terminals is getting more and more attention. Using the pictures acquired by the mobile terminal to extract and identify palmprint feature information has become a mobile terminal unlocking technology. Among them, the collected palmprint images often need to be positioned and segmented before feature extraction in order to obtain the same area. The palmprint sub-image, for this purpose to extract the outline of the palmprint, edge detection is a commonly used method. [0003] In the prior art, most of the palmprint edge detection algorithms are completed in the binary image by using the convolution mask in the differential operator to convolve each pixel i...
