Embodiment Construction

[0037] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0038] A target detection method for feature extraction of images based on a deep learning framework, comprising the following steps:

[0039] Step 1. The image is preprocessed by using the MCG algorithm to extract possible image blocks of the target position. Specifically include the following steps:

[0040] (1) Obtain the edge map of the image through the edge detection algorithm, and further obtain the contour map of the image, and obtain the UCM map through a series of processing on the contour map.

[0041] (2) Use the UCM map to obtain the superpixel points of the image, that is, each connected domain, and there is a dissimilarity value between any two adjacent regions.

[0042] (3) Merge the areas obtained in the above steps, merge N leaf nodes in pairs, and finally get N-1 non-leaf nodes, thus constructing a complete binary tree. The root ...

Abstract

The invention relates to a target detection method for feature extraction of images on the basis of a deep learning framework. The method is technically characterized in that the images are preprocessed on the basis of the MCG algorithm, and possible image blocks at target positions are extracted; the extracted image blocks are optimized on the basis of the MTSE algorithm; the obtained image blocks are iterated and adjusted to the size meeting the caffe framework input requirement through the superpixel optimization method; feature extraction is conducted on the image blocks through the caffe deep learning framework, and model configuration is finished through the R-CNN algorithm; obtained features are classified through the SVM algorithm to obtain a final result. The method is reasonable in design, the calculation quantity of the features is reduced by preprocessing the images, then deep features of the images are extracted through the caffe deep learning framework, objects can be represented better, the features are classified through the SVM classification algorithm, and a good detection result is obtained.

Description

technical field [0001] The invention belongs to the technical field of target detection, in particular to a target detection method for feature extraction of images based on a deep learning framework. Background technique [0002] Vision is an important sensory modality by which humans interact with the world around them. More than 80% of the information processed in the human brain comes from visual information, which ensures that we can intelligently perceive the world and make appropriate actions in our daily life, especially in today's rapid development of mobile smart devices, more and more image sensors are scattered around us and used by ourselves. The human visual system can detect and locate target objects from complex environments, which is the basic function of human vision. Computer target detection and recognition aims to use machines to detect and locate specific targets, and is the basis for target search and tracking. Object detection and recognition has a...
