Embodiment Construction

[0022] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0023] Considering that the PCNN model is proposed based on the biological optic neurocortex theory, the network parameters M and W can not only effectively describe the global information of the image, but also describe the change relationship of each pixel relative to the neighboring pixels. Therefore, according to the biological visual information contained in the image itself By setting the network parameters W and M adaptively based on information, the characteristics of the image itself can be accurately described globally and locally. Based on this, an embodiment of the present invention provides an image analysis method and device based on a PCNN model.

Abstract

The invention discloses an image analysis method and device based on a PCNN model. The image analysis method comprises the steps that a pixel is randomly selected from a current image; the maximum energy of the pixel and corresponding direction channels in adjacent domains is calculated by means of changing the size of a window of a visual information calculation model; the maximum size and effective direction of the visual information calculation model are determined according to the maximum energy of each direction channel; parameters W and M of the PCNN model are determined according to the maximum size and effective direction, wherein the M is a connection matrix of a feedback input domain, and the W is a connection matrix of a coupling connection domain; the current image is subjected to image analysis based on the PCNN model corresponding to the determined W and M. The image analysis method and device based on the PCNN model solve the problem that in the correlation technique, the self-adaptivity of the PCNN model is relatively poor.

Description

technical field [0001] The present invention relates to the field of image processing and analysis, in particular to an image analysis method and device based on a PCNN (Pulse Coupled Neural Networks) model. Background technique [0002] The parameters in the PCNN model can determine the performance of the model in the field of digital image understanding, analysis and pattern recognition. Therefore, various research schemes for setting PCNN network parameters have been proposed in the related art. According to the research content, it can be divided into: 1) Adaptive setting method for one or more parameters of PCNN based on the statistical information of the image; 2) Method for setting parameters of PCNN based on the receptive field; How to set network parameters. [0003] Most of the above PCNN models are parameter settings for images in a specific field, resulting in poor adaptability of the PCNN model. [0004] Aiming at the problem of relatively poor adaptability o...
