A new approach for contrast enhancement of chest radiograph image data is presented. Existing methods for image enhancement focus mainly on the properties of the image to be processed while excluding any consideration of the observer characteristics. In several applications, particularly in the medical imaging area, effective contrast enhancement for(More)
Wireless Multimedia Sensor Networks (WMSNs) are resource constrained (compared to the requirement of video communication), where the sensor nodes have limited bandwidth, energy, processing power and memory. Resource mapping is required in such networks, which is based on user requirements to offer better communication services as well as to use optimal(More)
This paper presents design of 4 Bit Flash Analog to Digital Converter using a latest comparator for voltage comparison called Threshold Modified Comparator Circuit (TMCC) and NOR ROM encoder in cadence environment using 90nm CMOS Technology. The TMCC comparators are designed to optimize the input offset voltages by systematically and consistently varying(More)
