Abstract

The invention discloses an image boundary detection method and a device, relates to the technical field of image processing, and aims to solve the problem that palm boundaries cannot be accurately detected in the prior art. The method mainly comprises the steps of performing equalization processing on a to-be-detected image according to a preset reference color to generate an equalized image; performing binarization processing on the averaged image to generate a boundary image; extracting an outer contour image of an object in the boundary image according to an edge detection algorithm; judging whether the outer contour image is a target image according to a support vector machine SVM algorithm; and if the judgment result is yes, marking the outer contour pixel points of the outer contourimage in the to-be-detected image. The method is mainly applied to the image recognition process.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image boundary detection method and device. Background technique [0002] Detecting image boundaries is usually applied in the process of image recognition. Taking the detection of palm boundaries as an example, this method is the basis of gesture recognition and palmprint recognition. When detecting the palm boundary, it is prone to background interference, such as the skin of the face and neck or clothing with a similar color to the skin color, etc., especially in the case of complex and changeable backgrounds, the background interference seriously affects the accuracy of palm boundary detection. [0003] In the prior art, by obtaining a gesture image, extracting the maximum contour of the gesture image within a set range; calculating the coordinate values ​​of multiple depression points in the maximum contour to obtain the average point of multiple depression point...
