After prediction algorithm is tesed and built, the team started to do research for the comparison methodology. our team found out that there is several possible method to do comparison such as doing a pixel comparison and etc. After, reading some article, we decided to use the SSIM(structural similarity index) calculation method as it is the most suitable that the team know for the team’s case. to ease up the team to understand and implement the SSIM calculation method our team referenced som ecode from Adrian Rosebrock which basedn on openCV to shows the visual difference of the image by ploting the difference with ploting library. The comparison however, require the image to be converted to grayscale image which is represented by 0 and 1 bit which present white and black respectively. the output of this algorithm is the box that mark the difference between the handwriting image.
