Now a days the cameras that are coming with smartphones have very large resolutions. For example, ASUS ROG 5s comes with a rear camera of 64 megapixel (along with two more rear cameras) and a front camera of 24 megapixel. These high-resolution cameras can produce pictures and videos that are very clear and large in dimensions.
In a rush to have very high-resolution pictures and videos, we often find our old collection of pictures and videos turned obsolete and dated. Imagine comparing your pictures from 2011 that were shot with an 8 megapixel digital camera (which was great for those times) with the present pictures captured by any decent smartphone.
So how do we bring our older pictures and videos to the same threshold as the ones produced by newer high-resolution cameras? We can use an open-source software called NiceScaler. It can increase the resolution of your pictures and videos by a factor of 2x or 4x. It is able to up-scale pictures and videos in the following formats: PNG, JPEG, BMP, WEBP, TIF and MP4, WEBM, GIF, MKV, FLV, AVI, MOV.
The program is fully portable and does not require installation on the local drive. The program has a large user interface which may not fit on smaller screens of laptops. It is advised to use at least a 21 inches screen so that you can use this program. In its user interface we can find three options – models to be used, upscale factor and whether to use GPU or CPU.
Among the deep learning artificial intelligence models are available three models – FSRCNN, ESPCN and, LAPSRN. We can select the image or video file using the drag-n-drop method. After selecting a desired up-scaling factor, we can click on the Upscale button. NiceScaler will process the file and save it in the same location where the program was run.
NiceScaler definitely does a better job of upscaling the images than your ordinary image editor. The output images look smoother and a casual inspection won’t reveal that it was created from a smaller size image.
