This is a paper in 2017 CVPR with over 500 citations. Label of the image is generated by cropping the 21X21 regions from it sequentially. Recently, Convolutional Neural Networks (CNNs) have achieved state of the art performance on SISR. The experimental results clearly show the effectiveness of MWCNN for image denoising, single image super-resolution, and JPEG image artifacts removal. These . The results quite good as shown below: An observation that can be made is that Deconv2D (when used instead of UpSampling2D), results in checkerboard artifacts. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. 1.Original historical footage of Israel's declaration of Independence and the footage colorized and restored using AI Super Resolution. It is a ratio of the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its representation.The deep convolutional model in SRCNN directly learns anend-to-end mapping between low and high-resolution images with little preprocessing.

Numerous super-resolution approaches [2] [3] [4][5][6] have been proposed to enhance the quality of the low image to a highresolution image for the support to detect the license plate. The results show that our methods and trails can achieve equivalent performance on most of the benchmarks compared with the previous state-of-art methods, and out-perform them in terms of the structural similarity. After that upscaling the image by 3x by bicubic interpolation; followed by downscaling it by the same. We used 21X21 dimension because when we feed 33X33 images to our classifier it output 21X21 images. Out of the 25k images, 200 each was kept aside for validation and test. Moreover, a condition is injected to resolve the problem of partial information loss associated with GANs. It used RMS loss and stochastic gradient descent opeimizer for training in this repository, but original one was trained by MSE loss (using same optimizer). Actually, there is no short form for the CNN network. News (2021-01): BSRGAN for blind real image super-resolution will be added.
