Abstract:
The application of image processing in the medical field is widely used among medical experts since it can help them by providing an earlier detection and treatment stages. Image enhancement plays an important role in medical images especially in diagnosing a tumor or cancer cells in an image. It will improve the visibility and detail of the image, which can help the expert’s diagnosis. The Ki67 is a nuclear protein that was widely used among the pathologists to measure the proliferation of tumour cells. This paper aimed to study the performance of different image enhancement techniques in segmenting Ki67 cells. In this study, the proposed system used three image enhancement techniques, which are contrast stretching, histogram equalization, and CLAHE technique. The enhancement techniques were applied to the colored images. The resultant images then were used as the input images to segment the Ki67 cells. The experimental results show that the contrast stretching technique produced higher results compared to other enhancement types.
