I am facing problem in reading Fourier domain of a given image. I don't understand what to interpret from it. For instance, consider this image.
Ok, so there is a dot in the middle, with some striking vertical and horizontal lines and there are also some circulating white lines which are low in intensity. What do I interpret from them? I basically converted the image to a monochrome image and then took the fourier transform of the monochrome image and displayed it along with original RGB image. Please help me to understand this. I tried every other resource but nothing got into my head. What are the uses of this interpretation? Also, in one of the answers here on DSP stackexchange, the images of sine and cosine were taken and then converted to spectrum which resulted white dots in it. I don't want to know that. I know that these dot represents the frequency component present in the sine and cosine. I want to understand everything with respect to my image only.
Thanks in advance!!
