    摘要: A multi-pass video encoder includes a video encoding module that encodes a video signal based on an initial configuration data set to generate an initial processed video signal and an initial output data set. An application coding control module generates the initial configuration data set and generates a first updated configuration data set based on both the initial processed video signal and the initial output data set. The video encoding module further encodes the video signal based on the first updated configuration data set to generate a first updated processed video signal and a first updated output data set.

    摘要: A metric representing the sum of variances for pixel blocks of a region of an image are used to identify the presence a video feature of the image, and a transcoding is performed responsive to identifying the presence of the video feature. The identified video feature can include, but is not limited to, a scene change, the presence of a black border region or a caption region, or the complexity of the image. The transcoding operation can include, but is not limited to, coding the image as an Intra-frame, omitting the content corresponding to the black border region or the caption region from the transcoded image or allocating a relatively lower bit budget for the black border region or a relatively higher bit budget to the caption region during transcoding of the image, or setting the bit budget for rate control during transcoding.

    摘要: A method and system for inspecting railway components. The method includes receiving a stream of images containing railway components, detecting a railway component in each image, generating a plurality of feature vectors for each railway component image, measuring the dissimilarity between the railway component and a set of railway components detected in preceding images, in a sliding window, based on the feature vectors.
