To find the veins in intravenous emergency injections, non-invasive feasible methods seem to be necessary. In another area in biometric identification, hand vein patterns can be used as other external identifiers are more probable to be damaged or forged. To achieve these goals, NIR back hand vein images are captured. In the proposed method, the NIR hand vein images are pre-processed and segmented...
Image Segmentation is necessary factor in the medical image processing. According to the current scenario of health care society, detection of brain tumor is a must. Automated brain disorder diagnosis with MR images is one of the challenging medical image analysis methodologies. Segmentation is used to separate the abnormal tumor portion in brain. These tumors are inhomogeneous, unsharp, and faint...
This paper describes an automated algorithm for plague detection in Intra Vascular Ultrasound images, using an adaptive border detection method for selection Region of Interest (RIO) and detect the soft and hard plague. As shadow appears behind the calcification plaque, it makes it difficult especially for soft plague. Our algorithm divided by two mail part; one, border detection and selection the...
Moving object segmentation is an important step toward development of any computer vision systems. In the present work, we have proposed a new method for segmentation of moving objects, which is based on single change detection method applied on Contourlet coefficients of two consecutive frames. We have chosen contourlet transform as it has high directionality and represents salient features of image...
One of the emerging areas in image processing is color image enhancement. It is the process of improving image quality such as human visibility, edge sharpening, improving the contrast, etc. It is mainly applicable in medical images, satellite images. An algorithm for color image enhancement has been proposed that perform enhancement in red, green, blue components separately. These components are...
Steganalysis is the aptitude of identifying stegogrammes that contain a secret message. To test the steganalysis algorithm touching the unusual Stego images to ensure its robustness. This paper proposes an active steganalysis method uses irregularity in the stego image or the specialized algorithm is used to detect the existence of stego image. DCT coefficients are intended for each block. Approximate...
In nonrigid image registration two problems make a challenging task. First the voxel intensity similarity and anatomical image similarity will not be equivalent. Second during imaging process some distortions such as unwanted rotations and monotonic gray-level fields may occur. Due to these problems image registration quality gets affected. To avoid these problems and to calculate efficiently Uniform...
The major issue in clinical laboratory is to produce a precise result for every test especially in the area of Red Blood Cell (RBC) count. The number of red blood cell is very important to detect as well as to follow the treatment of many diseases like anaemia, leukaemia etc. Red blood cell count gives the vital information that help diagnosis many of the patient's sickness. The old conventional method...
