After downloading the zip folder, unzip it and you will have the following directory structure. Asked: pip install numpy This allows for the usage of packages implementing multidimensional arrays. Solve Crimes by AI by doing just that (I know it was a ridiculous idea). And if I set it to something silly like 2000x2000 it becomes 1280x720. Why do we need to do that ? So in order to initiate the correct pre and post-processing pipelines, the module needs to know which model we will be using and what version meaning what scale 2x, 3x, 4x etc. How actually can you perform the trick with the "illusion of the party distracting the dragon" like they did it in Vox Machina (animated series)? Also I would raise a concern regarding these models that we must be careful using SR networks, for e.g. These models have been trained using DIV2K BSDS and General100 datasets which contains images of diverse objects but the best results from a super-resolution model is obtained by training them for a domain-specific task, for e.g if you want the SR model to perform best on pedestrians then your dataset should consist mostly of pedestrian images. In this post, you will first learn about some interesting hybrid branches (Semi-Supervised Learning and Self-Supervised Learning) of AI, AI industries etc. It's free to sign up and bid on jobs. The function above displays the original image along with the SR Image. If you havent done that then you can easily follow my installation tutorial. from cv2 import dnn_superres Initialize the Super Resolution Object First you have to create the dnn_superres constructor by the following command. One of the best things about this module is that It does the required pre and post processing internally, so with only a few lines of code you can do super resolution.
