Abstract

The invention provides a deep learning-based high-precision image fuzzy detection method, which comprises the following steps: (1) building a deep convolution neural network model CNN and carrying out initialization and inputting a detected image into the deep convolution neural network model CNN; (2) selecting different s scales for a to-be-detected image by the deep convolution neural network model to obtain image blocks of different scales; (3) carrying out feature extraction on the image blocks in the step (2) by the deep convolution neural network model to obtain single-scale fuzzy graphs according to six convolution layers; and (4) carrying out fusion processing on the different single-scale fuzzy graphs by the deep convolution neural network model for multiple times to obtain the fuzzy graphs. According to the method, a deep convolution neural network is applied to the problem image fuzzy detection, so that a fuzzy area in the image is accurately detected as the target.

Description

technical field [0001] The invention belongs to the field of image blur detection and relates to a high-precision image blur detection technology based on deep learning. Background technique [0002] The background technology involved in the present invention has: [0003] (1) Image blur detection (Blur detection): For image blur detection, previous work mainly focused on the manual selection of features and the optimization of energy functions. Selecting appropriate features or energy functions, different methods can be used to directly model the subject, such as the use of multi-directional gradient statistics methods to establish energy functions for fuzzy segmentation, local gradient statistics methods are also used to estimate the blur caused by object motion . Commonly used features are local energy spectrum slope, gradient histogram span, maximum saturation, and local autocorrelation consistency. There are some works to identify the type of blur and measure the con...
