Embodiment Construction

[0035] In the process of biological vision forming scene recognition, only the central fovea of ​​the human retina contains a large number of rod cells that can be clearly imaged, while the peripheral area can only be fuzzy imaged by cone cells, resulting in the need for micro-fibrillation (microsaccade, Also known as "micro-saccade", "micro-saccade"), the neural mechanism is to scan the scene by unconsciously and quickly turning the eyeballs to form an image of the entire scene. And in the process of microfibrillation, the blurred vision in the peripheral area of ​​the retina provides probabilistic regional cognition, forming a priori reference, and on this basis, combined with the clear vision of the fovea, a complete and clear scene cognition is formed.

[0036] A sample extraction method, comprising the steps of:

[0037] Step 1: Get the original image Oimg, shrink Oimg n times, where, L represents the length of Oimg, W represents the width of Oimg, obtains an image pyra...

Abstract

The invention belongs to the technical field of image processing. The invention discloses a sample extraction method and an image classification method based on hole convolution and residual link. According to the sample extraction method, an image pyramid of an original image is constructed, then convolution is carried out on the image pyramid, an identification result is extracted, a region identification image with a category label is finally obtained through methods of binarization, fuzzy clustering and the like, and finally a homologous reliable classification sample is obtained through image mapping. According to the image classification method based on cavity convolution and residual link, a completely self-adaptive deep learning classification network is constructed by a method ofsimulating clear vision in the central fovea, different types of unique feature modes are learned from homologous reliable samples of the images, and completely self-adaptive classification is carriedout on the images according to the learned feature modes.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a sample extraction and an image classification method based on atrous convolution and residual linking. Background technique [0002] Image classification is the most basic technical means in the hot machine vision and artificial intelligence. As the most basic image analysis method, image classification can reasonably combine various information from complex and redundant image data, so as to integrate information with certain characteristics into the same category and complete the classification. This technology can provide fast, accurate, and non-redundant prior references for a wide range of practical applications such as target recognition, detection, and tracking, and is the basis for various image analysis tasks. In particular, the image classification technology based on deep learning, based on the powerful cognitive advantages of the neural network...
