This Python project analyzes the blurriness of an image by calculating the high-frequency components using the 2D Fast Fourier Transform (FFT). The blurriness metric is determined by comparing the ...

We first investigate 2D quatemion Fourier transform (QFT) spectrum relationship between an image and its geometrically transformed counterpart from the aspects of gray images and color images ...

In this paper we present an efficient way of doing image reconstruction using the 2D discrete Fourier transform (DFT). We exploit the fact that in the frequency domain, information is concentrated in ...

Fun with Python and Quartz 2D A new primer from the Apple Developer Connection shows you how to put Python ... For maximum image-manipulation fun, try adding sips to the mix.
