Computer Vision - Teaching Computers to see the World

The sensor for the computer is a camera. In the case of a digital camera, the image that the camera sees appears in a rectangular grid on the back of the camera. This image can be downloaded to a computer and manipulated through a computer program called MATLAB.

MATLAB is an abbreviation of Matrixes Laboratory. In MATLAB an imported black and white image is stored on a two dimensional (mn) matrix. A color image is stored on a three dimensional matrix (m* n* 3).

In the world of computers, all colors are made up of three additive colors red, green and blue.

So in MATLAB, the first matrix is red, the second matrix is green and the third matrix is blue.

I learned how to program in MATLAB. I was able to convert colored pictures to black and white. I was able to take a color image and separate each channel red, blue and green. I also learned how to take two images and create a new image using half of the first image and half of the second image in both a vertical and horizontal layout.

For my final project, I learned about homography. Homography is the relation between two figures, such that any point of the one figure corresponds to one point in the other, and vise versa.
