Abstract: A method for calibrating a vehicular camera of a vehicular vision system includes placing a target with a first portion having a first geometric pattern and a second portion having a second geometric pattern within the field of view of the vehicular camera, and capturing image data with the camera representative of the field of view of the vehicular camera. Two edges of both portions of the target are detected, and edge pixels of the detected edges are determined. First and second vanishing points of the target in the captured image data are determined based on the determined edge pixels of the respective first and second portions of the target. Camera orientation is determined based on location of the determined first vanishing point relative to location of the determined second vanishing point. The vehicular camera is calibrated based on the determined camera orientation.

Abstract: Certain aspects of the present disclosure are directed to methods and apparatus for compressing video content using deep generative models. One example method generally includes receiving video content for compression. The received video content is generally encoded into a latent code space through an auto-encoder, which may be implemented by a first artificial neural network. A compressed version of the encoded video content is generally generated through a trained probabilistic model, which may be implemented by a second artificial neural network, and output for transmission.

Abstract: Innovations in the area of prediction of block vector (“BV”) values improve encoding or decoding of blocks using intra block copy (“BC”) prediction. For example, some of the innovations relate to use of a default BV predictor with a non-zero value. Other innovations relate to use of a selected one of multiple BV predictor candidates for a current block. Still other innovations relate to use of a skip mode in which a current intra-BC-predicted block uses a predicted BV value.

The side information determination section (21) sets a quantization parameter for each macroblock in such a manner that a difference between quantization parameters for each pair of macroblocks with successive encoding orders is equal to one of n difference values, and transforms the difference into one of n indices with respect to each pair. The side information encoding section (22) generates a binary sequence having a length corresponding to the size of the absolute value of the index. The total of absolute values of the n indices is smaller than the total of absolute values of the n difference values.
