Colon cancer is one of the leading cancers in both men and women across the globe. The incidence is especially high in developed countries and urban settings. Colonoscopy has been the established procedure for screening and early detection of colon cancer. This procedure involves insertion of a colonoscope with a video camera to examine the inner lining of the colon for suspicious polyps and growths...
Though the classical robotics is highly proficient in accomplishing a lot of complex tasks, still it is far from exhibiting the human-like natural intelligence in terms of flexibility and reliability to work in dynamic scenarios. In order to render these qualities in the robots, reinforcement learning could prove to be quite effective. By employing learning based training provided by reinforcement...
Background Subtraction is a preliminary technique used for video surveillance, moving object detection, human machine interaction, gait recognition, multimedia applications etc. A range of algorithms have been introduced over the years and tested over different databases with ground truth. The goal of this study is to provide a comparative analysis of available background subtraction algorithms classified...
Glare is a hardware problem that occurs because of the light trapped in the lens elements. It is a common problem faced in photography when trying to capture image of a scene having bright source in it or taken in a very bright environment. Glare can hide useful information in the image, can make foreground objects blurry and deformed. In this paper, we propose a novel method to detect glare, mainly...
Real-time detection of gait events play a vital role in movement dependent control applications such as rehabilitation for lower limb amputations. It also helps in determination of spatio-temporal and kinematic parameters. Gyroscopes, inertial sensors, magnetometers and foot sensors are popular in the detection of gait events. They need to be mounted carefully, or foot should be placed specifically...
Target tracking is an important requirement in the battle field. The proposed target classification algorithm is a video based surveillance system. This kind of system is very useful in tracking and classification of targets. The target area and tyre detection are the key steps of this algorithm used for detection of target. A target classification algorithm based on area and tire axle spacing was...
The Real time image processing is always in high demand for many applications used in security system, remote sensing, manufacturing process and multimedia, those require to have high performance. Based on that requirement, image processing systems have been proposed in this paper using a heterogeneous platform called TMS320DM642. The platform has an FPGA chip and a DSP processor. The FPGA chip is...
Gait analysis has applications not only in medical, rehabilitation and sports, but it can also play a decisive role in security and surveillance as a behavioral biometric factor. This paper discusses gait parameters extraction technique without using makers or sensors. Videos from a home digital camera are analyzed and a silhouette image based technique is used to identify gait parameter such as step...
Most digital cameras use color filter arrays of different patterns to capture color image. The output of the color filter array is a sampled version of the original color image. Demosaicing algorithms are used to reconstruct the original color image from this sampled version. Medical image analysis is increasing day by day. The amount of data to be saved is also on the increase. Standard compression...
Commercial telerobotic surgery systems for soft tissue surgery are generally limited to visual imaging, though it is possible to simultaneously view picture-in-picture visualization of another workstation. However, it is not easy to correlate such information with the primary endoscopic view since it may not relate to the surface visible in the visual endoscopic images. As critical surfaces as well...
With the increasing popularity of robotic surgery, several studies in the literature have investigated automatically assessing skill measures based on motion and video data captured from these systems. A range of simulation environments for robotic surgery are now in development. Skill assessment in these environments has so far only focused on evaluating the utility and validity of statistics such...
