Color Image Processing

Color Image Processing is our 4th Exercise. The objective of this exercise is to detect an object using color spaces. For this exercise our object is a pig with green tag. We need to detect the pig and the green tag.

I use HSV color space for detecting the green tag and YCRCB color space for detecting the pig. The range of minimum and maximum for the pig detection is hardcoded. I use this http://www.wseas.us/e-library/conferences/2011/Mexico/CEMATH/CEMATH-20.pdf as reference for detecting the pig.

I cleaned the images using opening method with a kernel size of 20.

Here are my sample outputs detecting the green tag:

Some bad outputs detecting the pig:

The rest of the pig detection are okay:

Document Layout Analysis

Document Layout Analysis is our second exercise. Using the three images above our program needs to do the following: Individual characters are boxed Individual words are boxed Lines are boxed Paragraphs are boxed The paragraphs with margins I used a bottom-up approach for this exercise. It means that I started detecting and boxing the letters to words to line to paragraph and lastly to the paragraph with margin. I created a function for each of the objectives. I used a trial and error approach for determining the appropriate kernel size for the specific function. I have a very simple step for every objectives: Load the images. Assigning of output images Convert images to grayscale Cleaning the images using Otsu's Thresholding method. (with the inversed binarized image) Assigning kernel size (1 or 2 kernels depending in the objective) Morphological Operations (Dilation, Erosion, Closing and Opening) Find the Contours Box the contours (I added some offs...
