[Activity 7] Image segmentation is taking a part of the image so that further image processing can be done to it. For example, if we have a grayscale image of a check, we can use image segmentation to find the parts of the check that have writing/text on it. To properly segment the grayscale image,… Continue reading Image Segmentation

2D Fourier Transform Applications and Properties
One property of Fourier Transformations is anamorphism. Since the FT space is in the inverse dimension of the original space, what is wide in one axis will become narrow in the spatial frequency axis. Anamorphism works independently on each axis, so you can expect that patterns with different dimensions along each axis will have a… Continue reading 2D Fourier Transform Applications and Properties
