Semiconductor chips are made increasingly smaller, thanks to improved design techniques and process scaling. Sometimes the bottleneck is not the chip itself but the package size due to many necessary pins. To help reduce the number of package pins, the chip should use less pins by sharing or reusing pins if possible. Therefore, single-ended RF input/output is used for transceiver, and the same pin is shared between RX and TX. A receiver (RX)-transmitter (TX) impedance co-matching method uses multiple bondwires for transceivers sharing one input/output (I/O) pin between RX and TX. The RX input impedance and TX output impedance are transformed closer to each other or even to the same impedance, which makes it possible to get the best RX and TX performance with just one matching network. The chip area is also saved without using on-chip inductors.

Motion adaptive shading increases rendering performance for real-time animation in graphics systems while maintaining dynamic image quality. Each frame of an animation is statically displayed within a refresh interval, while a viewer's eyes move continuously relative to the image when actively tracking a moving object being displayed. As a result, a statically displayed frame is essentially smeared across the viewer's continuously moving retina over the lifetime of the frame, causing a perception of blur referred to as an eye-tracking motion blur effect. A region of an image depicting a moving object may be rendered at a lower shading rate because eye-tracking motion blur will substantially mask any blur introduced by reducing the shading rate. Reducing an average shading rate for rendering frames reduces computational effort per frame and may advantageously allow a rendering system to operate at a higher frame rate to provide a smoother, clearer visual experience.

A system includes a first sensor and a sensor client. During an initial time interval, the sensor client receives top-view images generated by the first sensor and detects contours in the images. The sensor client determines, based on the contours, regions of the top-view images generated by the first sensor to exclude during object tracking. During a subsequent time interval, the sensor client receives a second top-view image generated by the first sensor and detects a contour in the image. The sensor client determines pixel coordinates of the second contour and determines whether at least a threshold percentage of the second pixel coordinates overlap with the region to exclude during object tracking. If at least the threshold percentage of the second pixel coordinates overlap with the region to exclude, a position for tracking the second contour is not determined.

The present invention relates to a learning method of generative adversarial network (GAN) with multiple generators for image denoising, and provides a generative adversarial network with three generators. Such generators are used for removing Poisson noise, Gaussian blur noise and distortion noise respectively to improve the quality of low-dose CT (LDCT) images; the generators adopt the residual network structure. The mapped short connection used in the residual network can avoid the vanishing gradient problem in a deep neural network and accelerate the network training; the training of GAN is always a difficult problem due to the unreasonable measure between the generative distribution and real distribution. The present invention can stabilize training and enhance the robustness of training models by limiting the spectral norm of a weight matrix.
