Contrast Enhancement of Computed Tomography Brain Images for Ischaemic Stroke Detection
Nowadays, the manual examination of computed tomography (CT) brain images is still practised. Depending on human expertise and experience, the ischaemic stroke detection is always prone to human visual error. Therefore, image processing techniques are applied to enhance image contrast for improved d...
