Image Sensor with Image Smoothing Capability Using a Neuron MOSFET
نویسندگان
چکیده
A pixel output node of the image sensor is connected to the input gates of several neuron MOSFETs which are implemented on the periphery of the imaging area. The pixel output is weighted by the input gate's capacitance value and summed up on the floating gate. Thus the filter characteristic is determined by the input gates' capacitance values and the number of pixels connected to the input gates of a neuron MOSFET. An active pixel sensor (APS) approach is suitable for the architecture because of its large driving capability.

متن کاملPAIRED ANISOTROPIC DISTRIBUTION FOR IMAGE SELECTIVE SMOOTHING
In this paper, we present a novel approach for image selective smoothing by the evolution of two paired nonlinear partial differential equations. The distribution coefficient in de-noising equation controls the speed of distribution, and is determined by the edge-strength function. In the previous works, the edge-strength function depends on isotropic smoothing of the image...
متن کاملOptimization of Energy Consumption in Image Transmission in Wireless Sensor Networks (WSNs) using a Hybrid Method
In wireless sensor networks (WSNs), sensor nodes have limited resources with regard to computation, storage, communication bandwidth, and the most important of all, energy supply. In addition, in many applications of sensor networks, we need to send images to a sink node. Therefore, we have to use methods for sending images in which the number and volume of packets are optim...
