Target integrity detection method and device

Abstract

The embodiment provides a target integrity detection method and a device. The method comprises steps that an original image of a target is inputted into a neural network to acquire a thermodynamic diagram of the original image, and pixel values of the thermodynamic diagram represent pixels of the corresponding positions of the original image belonging to probability of the target; edges of the target in the original image are determined according to the thermodynamic diagram; and whether integrity of the target in the original image is realized is determined according to the edges. Through the method and the device, when integrity of the target in the original image is detected, robustness of interference signals such as busy background of the original image can be realized, moreover, on the condition that the thermodynamic diagram is acquired in the neural network, subsequent operation can be accomplished only through several relatively simple image processing steps, and usability is improved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for detecting object integrity. Background technique [0002] With the continuous development of image processing technology and the continuous enhancement of the computing power of computing devices, more and more application scenarios need to automatically detect the integrity of the target in the image. For example, when a user handles banking, communication, and other related procedures that require real-name authentication, it is often necessary to archive the image of his identity-related certificate as a record. Since the archived document images need to be recalled in the future, there are requirements on the quality of the images. One of the important requirements is the integrity of the document in the image. Taking the ID card as an example, the general requirements are: 1. The ID card is completely visible in the image and is not blocked b...

Problems solved by technology

That is to say, for existing target integrity detection schemes, when the original image includes complex backgrounds in addition to the target, especially interference such as text and stripes, it is difficult to obtain a clear real edge of the target, so it is difficult to Accurately detect whether the target is complete in the image
