1. Temple University Summer Research Progress: Week 4 – GUI Development George Fava Department of Electrical and Computer Engineering Temple University URL:

2. Temple University: Slide 1 GUI Progress Version 1.0 Designed using GUIDE – MATLAB’s GUI development environment Basic Features: Input and Output plots, Reset Plot Button, Output Plot Button, Image Selection menu, and Image viewing toolbar

3. Temple University: Slide 2 Main GUI Issue Data collecting algorithm is not quite right Flat contour = flat frequency response

4. Temple University: Slide 3 “Soft” GUI Issues Image axes get cluttered when switching between image data “Drawing” lines are not completely removed during the refresh

5. Temple University: Slide 4 Plans for the GUI Fix the data selection algorithm – the correct pixel “intensity” values are not being selected and used for the FFT calculation * Re-work the old code * Try alternative methods (freehanddraw, ginput, imfreehand, etc.) Correct the “soft” issues with the GUI – minor changes to the.m-file Add any more user-desirable features
