Abstract :
Heart failures are of increasing importance due to increasing life expectation. For clinical diagnosis parameters for the condition of hearts are needed and can be derived automatically by image processing. Accurate and fast image segmentation algorithms are of paramount importance for a wide range of medical imaging applications. In this paper, we present a method using heat equation with variable threshold technique towards seeds selection in random walk based image segmentation.
