How does image classification increase accuracy?

Add More Layers: If you have a complex dataset, you should utilize the power of deep neural networks and smash on some more layers to your architecture.

These additional layers will allow your network to learn a more complex classification function that may improve your classification performance.

Does reducing image size reduce quality?

Compressing JPEG images downgrades the quality of the image. … As a result, the resolution of each image is significantly different. If you reduce resolution, the number of pixels will be cut down resulting in a pixelated image. However, when you compress file size, a different algorithm will be applied.
