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...

UX Research: Understanding User Needs and Behaviors

As someone who has recently started a UX course on Coursera, I have learned that UX research is a critical aspect of the design process. The purpose of UX research is to gain a deep understanding of the users, their needs, and behaviors. This information is used to inform design decisions and create products and services that meet the needs and expectations of the users. There are several methods that can be used for UX research, including: Surveys: Surveys are a quick and easy way to gather information from a large number of users. They can be administered online or in person and can be used to gather information about demographics, user behavior, and product or service usage. User interviews: User interviews are one-on-one conversations with users. They are an effective way to gather in-depth information about a user's experiences, thoughts, and opinions. User interviews can be conducted in person or over the phone and can last anywhere from 30 minutes to an hour. User testing: U...
