Image division method simulating human vision

Abstract

The invention discloses an image division method simulating human vision. The method comprises the following steps of: 1, performing saliency detection on a target image to obtain a pixel saliency degree map; 2, ordering saliency points in the pixel saliency degree map according to the saliency degree; 3, selecting the first N saliency points to be used as a gazing point, and using the gazing point as the center to form a local region with the maximum information entropy, wherein the local region forms a gazing region; 4, performing random sampling in the gazing region, and performing equivalent pixel random sampling on the outside of the gazing region; and 5, obtaining a classification model by using an extreme learning machine training strategy; classifying all pixels of the target image; using a pixel region divided into a positive sample as a first division result; repeating the step 3 to the step 5 to obtain a repeated division result; and recording the region when the division result is stable; repeating the step 2 to the step 5 until no region capable of being gazed exists in the image. The image division method simulating human vision has the advantage that the human vision is simulated through gazing point ordering and a neural network model, so that the division on the target image is realized.

Description

technical field [0001] The invention relates to the technical field of human vision simulation, in particular to an image segmentation method for simulating human vision. Background technique [0002] With the development of information technology, computer vision has been widely used in low-level feature detection and description, pattern recognition, artificial intelligence reasoning and machine learning algorithms and other fields. However, traditional computer vision methods are usually task-driven, that is, many conditions need to be limited, and corresponding algorithms should be designed according to actual tasks, which lacks versatility; it needs to solve high-dimensional nonlinear feature spaces, large data volumes, problem solving and real-time processing, etc. These problems make its research and application face great challenges. [0003] The human visual system is able to work efficiently and reliably in different environments, which has the following advantage...

Problems solved by technology

However, when the mechanism of human visual perception is not yet fully understood, it is still difficult to construct machine vision with human visual characteristics. If a machine vision system that simulates human vision can be constructed, the saliency information Extraction and segmentation will inevitably have an important impact on the field of computer vision applications.
