Description: Color fundus images often show important lighting variations, poor contrast and noise. In order to reduce these imperfections and generate images more suitable for extracting the pixel features demanded in the classification step, a preprocessing comprising the following steps is applied: 1) vessel central light reflex removal, 2) background homogenization, and 3) vessel enhancement. Next, a description of the procedure, illustrated through its application to a STARE database fundus image, is detailed. Platform: |

Description: A new and efficient algorithm for high-density salt
and pepper noise removal in images and videos is proposed.The existing non-linear filter like Standard Median Filter
(SMF), Adaptive Median Filter (AMF), Decision Based
Algorithm (DBA) and Robust Estimation Algorithm (REA)
shows better results at low and medium noise densities. At high
noise densities, their performance is poor. A new algorithm to
remove high-density salt and pepper noise using modified
sheer sorting method is proposed Platform: |

Description: Brain tumors are created by abnormal and uncontrolled cell division in brain itself. If the growth becomes more than 50 , then the patient is not able to recover. So the detection of brain tumor needs to be fast and accurate. The objective of this paper is to provide an efficient algorithm for detecting the edges of brain tumor. The first step starts with the acquisition of MRI scan of brain and then digital imaging techniques are applied for getting the exact location and size of tumor. MRI images consist of gray and white matter and the region containing tumor has more intensity. So, first noise filters are used for noise removal and then enhancement techniques are applied to the given MRI scan of brain. After that the basic morphological operations are applied for extracting the region suffering from tumor. And then verification of region detected is done by using watershed segmentation. Platform: |
