Christos N. Stefanatos's Projects
Undertook an optional project for the course: "Introduction to computers" , taught by Dr Leonidas Alexopoulos , head of Bio engineering department @National Technical University of Athens. Project involved writing matlab commands to calculate the percentage of a lab plate that was covered with cells ( cell confluency). It included: 1. Converting the image to gray scale and applying contrast and object edge corrections. 2. Converting grayscale image to a logical image ( black or white pixels (0 not cell ,1 cell coverage ) through the use of a modular threshold level 3. Calculating the percentage of the pixels with cell coverage over the total pixels. 4. Integrating the above functions into a graphical user interface that allows browsing for appropriate images , modifying the threshold level with the use of slider ( while providing default level as well) displaying the stages of image conversion process and finally displaying the cell confluence percentage. 5. Presenting the algorithm and process functionality in class.
