<p>Deblurring of motion images is a part of the field of image restoration. The deblurring of motion images is not only difficult to estimate the motion parameters, but also contains complex factors such as noise, which makes the deblurring algorithm more difficult. Image deblurring can be divided into two categories: one is the non-blind image deblurring with known fuzzy kernel, and the other is the blind image deblurring with unknown fuzzy kernel. The traditional motion image deblurring networks ignore the non-uniformity of motion blurred images and cannot effectively recover the high frequency details and remove artifacts. In this paper, we propose a new generative adversarial network based on multi-feature fusion strategy for motion image deblurring. An adaptive residual module composed of deformation convolution module and channel attention module is constructed in the generative network. Where, the deformation convolution module learns the shape variables of motion blurred image features, and can dynamically adjust the shape and size of the convolution kernel according to the deformation information of the image, thus improving the ability of the network to adapt to image deformation. The channel attention module adjusts the extracted deformation features to obtain more high-frequency features and enhance the texture details of the restored image. Experimental results on public available GOPRO dataset show that the proposed algorithm improves the peak signal-to-noise ratio (PSNR) and is able to reconstruct high quality images with rich texture details compared to other motion image deblurring methods.</p> <p>&nbsp;</p>

Aiming at the problem that the existing posture recognition algorithms can not fully reflect the dynamic characteristics of athletes' posture, this paper proposes a CenterNet-SPP model based on multi-feature fusion algorithm for basketball posture recognition. Firstly, motion posture images are collected by optical image collector, and then gray scale transformation is performed to improve the image quality. Furthermore, body contour and motion posture region are obtained based on shadow elimination technology and inter-frame difference method. Finally, radon transform and discrete wavelet transform are used to extract the motion posture region and body contour, and the two complementary features are fused and then input into the CenterNet-SPP network to realize the final posture recognition. Experimental results show that the recognition accuracy of the proposed method is higher than that of other new methods.
