摘要： A current sensing data read/verify process and sense amplifier is described that senses memory cells of a non-volatile memory array utilizing a current sensing process that places a current source to provide current to the bit line. The voltage level of the bit line is then set by the current provided by the current source and the current sunk from the bit line through the selected memory cell to the source line, which is dependent on the threshold voltage of its programmed or erased state. If the selected memory cell is erased, current flows through the memory cell to the source line and the bit line voltage falls. If the selected memory cell is programmed, little or no current flows through the cell, and the bit line voltage rises and is sensed by the sense amplifier.

摘要： Methods and systems for high-resolution image manipulation are disclosed. An original high-resolution image to be manipulated is obtained, as well as a driving signal indicating a manipulation result. The original high-resolution image is down-sampled to obtain a low-resolution image to be manipulated. Using a trained manipulation generator, a low-resolution manipulated image and a motion field are generated from the low-resolution image. The motion field represent pixel displacements of the low-resolution image to obtain the manipulation indicated by the driving signal. A high-frequency residual image is computed from the original high-resolution image. A high-frequency manipulated residual image is generated using the motion field. A high-resolution manipulated image is outputted by combining the high-frequency manipulated residual image and a low-frequency manipulated image generated from the low-resolution manipulated image by up-sampling.

摘要： Methods and systems for fully-automatic image processing to detect and remove unwanted people from a digital image of a photograph. The system includes the following modules: 1) Deep neural network (DNN)-based module for object segmentation and head pose estimation; 2) classification (or grouping) of wanted versus unwanted people based on information collected in the first module; 3) image inpainting of the unwanted people in the digital image. The classification module can be rules-based in an example. In an example, the DNN-based module generates, from the digital image: 1. A list of object category labels, 2. A list of object scores, 3. A list of binary masks, 4. A list of object bounding boxes, 5. A list of crowd instances, 6. A list of human head bounding boxes, and 7. A list of head poses (e.g., yaws, pitches, and rolls).

摘要： In one embodiment, an apparatus an amplifier configured to receive an asymmetric signal. A first resistance is coupled between an input node and an output node of the amplifier, the input node receiving the asymmetric signal. A second resistance is coupled to the input node of the amplifier. The second resistance includes a linear resistor. A third resistance is coupled to the second resistance. The third resistance is varied to adjust an amount of asymmetric correction provided by the amplifier to correct the asymmetric signal at the output node. The amount of asymmetric correction is a function of the first resistance and a combination of the second resistance and the third resistance.
