The images are rotated using the self-defined code for rotation instead of the OpenCV inbuilt function. When an image is rotated by 45 degrees for 8 times, it does not produce the same result as when it is rotated by 90 degrees for 4 times. This is because, when an image is rotate...

Image Size Adjustment: Using the OpenCV library, we adjust all images to a uniform size of 112x112 pixels, thereby ensuring the consistency of the input data, which is a prerequisite for CNN models that require fixed-size input. 2.
