it will highlight the edges but it will also sharp the veins and if thresholding is applied it will extract the disc but produces discontinuity and overall shape of disc cannot be recognized as shown

If sharpening is applied after smoothing still it will sharp the veins within the image and does not produce the desired results as the information of veins produces discontinuity after thresholding so they should be completely eliminated from disc. For filling up discontinuity other techniques like morphology can be applied but it wasn’t covered yet and the idea was not much clear which is the limitation here. So it is concluded that first we apply smoothing to smooth out the effect of edges (veins) and then we apply thresholding to separate out the portion of disc from overall image. I have applied erosion using imerode command to erode the extracted area and then imfill command fills the gaps within a patch if any.

Limitations: This technique does not retain the exact shape of desired object especially for images which have less gray level differences from their neighboring pixels because if there is less difference in gray level and thresholding is applied after smoothing either it will included the unwanted surrounding pixels or it will discard the wanted pixels.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
