2.1 Image deblurring Common formulas for non-uniform fuzzy models. (1)where is a blurred image, is an unknown blur kernel determined by the motion field M, is a potentially clear image, * denotes convolution, and N is extra noise. In recent years, with the development of deep learning,...
Thus, the model obtained through this alternative training will be more suited to achieving image super-resolution for the fiberscope with a sub-millimeter diameter. The structure of the conditional residual module is shown in Figure 4c, which consists of two 3 × 3 convolutions and a dual-...
Design a new degradation model to synthesize LR images for training: 1) Make the blur, downsampling and noise more practical Blur:two convolutions with isotropic and anisotropic Gaussian kernels from both the HR space and LR space Downsampling:nearest, bilinear, bicubic, down-up-sampling ...
Two con- secutive frames are firstly followed by a few convolution layers and then fused with the Ot−1. The local flickering network is trained with a simple temporal consistency loss Llocal to remove local flickering artifacts: \mathcal {L}_{local}(O_t,O_{...
In BID, the blurred image is written as the convolution of the blur kernel and the latent clean image. Likewise, in BCD, following the Beer-Lambert law, once the observed RGB histological image is transformed to the OD space, it can be expressed as the product of the color-vector matrix...
The symbol ⊗ denotes a two-dimension convolution operator. The goal of infrared image Update the latent infrared image f To update the latent infrared image, the third term with respect to blurry function is dropped. Then, the cost function is simplified asQ(f)=12||f⊗h-g||22+αρ...
The sentence features are learned using rectangular convolution kernels or varying sizes. A decision strategy is also introduced for detection of long texts. A novel technique for text steganalysis was proposed by Bao et al.14 using Attentional Long-Short Term Memory (LSTM)-Convolutional Neural ...
