Updates

- Successfully separated the background image from a series of slides (see Fig 1)
- Extracting of foreground images from slides (see Fig 2)
- Detected some memory leaks which caused program to be slow

- Background extracted may contain missing or distorted pixels which may cause some foreground images to be unreadable.
- Tried to smooth the images extracted by:
a) Taking the dominant colour of the surrounding pixels
b) Taking the average rgb values of the surrounding pixels
- Results unsatisfactory

- Started on block segmentation
- Successfully implemented a code to push all the pixels to the left (see Fig. 3) and to the bottom to form necessary histograms for segmentation

TO DO:
- Refine the background / foreground extraction method to produce better quality output
- Analyse the histograms produced in order to segment the images
