1Shane Christy 30 January 2007 SUR 3331L Lab 2 The primary purpose of this lab was to analyze different properties of the images and determine how they relate to certain features on the photograph. To do this we analyzed distances, pixels, pixel size, resolution, and dots per inch (dpi). 1. Determine the size of the football stadium in pixels. To start everything off, the image had to opened in paint. After that, paint had a “coordinate system” we could assume. Using the cursor and scrolling to the corners of the football field, notes were taken of the two sets of the coordinates of the long end of the field (two corners). Then the distance formula was applied to find the distance of the field, in pixels, to be 174.83 pixels. After finding the dimensions of a football field (100 yards x 50.3 yards), pixels per yard could be calculated: Multiplying 1.75 pixels by 50.3 yards yields a value of 93.275 pixels. Therefore, the size of the field in pixels is 174.83 pixels by 93.275 pixels.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
