# Lecture 35 Blog, ECE438 Fall 2010, Prof. Boutin

Monday November 15, 2010 (Week 13) - See Course Outline.

We began the lecture with a proof of the linear filtering view of the STFT. Then we obtained a formula to reconstruct a signal from its STFT. This concluded the material on speech processing. We then began talking about image processing. Since images are signals depending on two (space) variables, we defined the 2D Fourier transform, which is also called the "continuous-space Fourier transform".
