A floating two-terminal unipolar current limiting circuit arrangement implemented with enhancement mode devices and bipolar devices with a unique voltage-current operation curve. This operation curve makes this device particularly advantageous to instrumentation systems that are intended to experience large voltage transients and long-term exposure to voltages that would normally damage measurement equipment. The present current limiting device is designed to have a large impedance value prior to a “turn-on” voltage, then quickly transitions to a low-impedance state. When the conducted current exceeds a setpoint or a high-voltage event occurs, the current limiting device further transitions to the “cutoff” region, which transition resumes the initial high-impedance state. In one embodiment the threshold current may be set with internal components, while a further embodiment allows the current setpoint to be set by external components. The current limiting device designs according to the present embodiments allow for series scaling and parallel scaling. |

An image processing method is configured to split a deconvolution kernel according to a preset splitting mode to obtain a sub-convolution kernel. And then, determining an original sub-matrix corresponding to the sub-convolution kernel, according to parameters of the sub-convolution kernel and an image feature matrix, and performing a convolution operation on the original sub-matrix corresponding to the sub-convolution kernel by using the sub-convolution kernel to obtain a deconvolution sub-matrix corresponding to each sub-convolution kernel; determining a target feature matrix according to the deconvolution sub-matrix corresponding to the sub-convolution kernel. When performing the deconvolution operation by the method, the image feature matrix doesn't need to perform tic-tac-toe filling to reduce a storage space occupied in the deconvolution operation process; in addition, since zero filled in the tic-tac-toe isn't participated in the deconvolution operation, calculation amount can be greatly reduced, and calculation efficiency of the deconvolution operation can be improved. |

Automatic image warping for warped image generation
Techniques and systems are provided for configuring neural networks to perform warping of an object represented in an image to create a caricature of the object. For instance, in response to obtaining an image of an object, a warped image generator generates a warping field using the image as input. The warping field is generated using a model trained with pairings of training images and known warped images using supervised learning techniques and one or more losses. The warped image generator determines, based on the warping field, a set of displacements associated with pixels of the input image. These displacements indicate pixel displacement directions for the pixels of the input image. These displacements are applied to the digital image to generate a warped image of the object. |

Geometric transformation matrix estimating device, geometric transformation matrix estimating method, and program
An object is to make it possible to precisely infer a geometric transformation matrix for transformation between an image and a reference image representing a plane region even if correspondence to the reference image cannot be obtained. A first line segment group extraction unit 120 extracts, out of a line segment group in an image, line segments that correspond to a direction that is parallel or perpendicular to a side of a rectangle included in the image, from the inside of the rectangle, takes the extracted line segments to be a first line segment group, and extracts a plurality of line segments different from the first line segment group out of the line segment group. An endpoint detection unit 150 detects four intersection points between ends of the image and two line segments that are selected from line segments that correspond to a direction that is parallel or perpendicular to a side of the rectangle and are extracted from a plurality of line segments obtained by transforming the different line segments using an affine transformation matrix in which an angle of the first line segment group relative to a reference direction of the image is used as a rotation angle. A homography matrix inferring unit 160 computes a geometric transformation matrix based on the affine transformation matrix and a homography matrix computed based on correspondence between the four intersection points and the four vertexes of the rectangle in a reference image. |
