I am a beginner in image processing. I started with opencv . Now there is a fundamental confusion to me . One is thresholding and one is image transformation . I am confused in these two parts.Till now i have understood couple of things: 1. Input image has to converted into Grayscale. 2. After that have to remove noise. 2.1 Now to remove noise what should i use thresholding or DFT techniques, when i read , both of them are used to remove noises.
Is my understanding right? Please guide me .
Thanks
