Temple University Summer Research Progress: Week 2 – Extraction of Data George Fava Department of Electrical and Computer Engineering Temple University URL:

Temple University: Slide 1 Data Extraction -- Part I Last week: data was extracted along zero and ninety degree lines The “Z” or height data was extracted The Fourier Transform was computed for a visualization of the frequency response This week: completed data extraction along an N-degree line Started with 45 and -45 degrees

Temple University: Slide 2

Temple University: Slide 3 Data Extraction -- Part II Created a function that: takes in an array of angles x and y coordinate -- to specify the "origin" of the image or data outputs the previous plot for each angle that is specified for any x/y coordinate Needed a way to extract this data for more than just 4 angles

Temple University: Slide 4 Function Example

Temple University: Slide 5 Function Example

Temple University: Slide 6 Issues with the Function When the x or y coordinate is greater than the half-way point in the image, the function fails to extract all the data This is no doubt an indexing error, but I could not get it to work with every angle all the time. This will be fixed.

Temple University: Slide 7 Future Plans Create a GUI that will take in an image All the user to draw a line anywhere on the image Extract the data along this line and compute an FFT Hydrology Project
