CPC Class H04N

A method of encoding video including: writing a plurality of predetermined buffer descriptions into a sequence parameter set of a coded video bitstream; writing a plurality of updating parameters into a slice header of the coded video bitstream for selecting and modifying one buffer description out of the plurality of buffer descriptions; and encoding a slice into the coded video bitstream using the slice header and the modified buffer description.

A telescopic pole mounting system is provided. The system comprises an adjustable spacer, a first end of the spacer coupled to a bracket and a clamp that partially encircles a vertical pole, ends of the clamp attached to the bracket. The system also comprises a cup attached to the spacer, movement of the cup causing one of expansion and contraction of the spacer. The system also comprises a telescopic pole that attaches to the cup, and raises and lowers the coupled clamp, spacer, and cup when the clamp is in loosened state. The telescopic pole also turns the cup in a first direction to expand the spacer and push the bracket away from the vertical pole, thus tightening the clamp about the vertical pole. The telescopic pole also turns the cup in a second direction to contract the spacer, thus loosening the clamp about the pole.

A method for assessing tyre tread depth and/or tyre condition by taking and analysing a camera image or images of a tyre using portable instrumentation.

An image processing system, an imager, an area detection method, and a computer program easily and highly accurately detecting an area where a target object exists in an image acquired by imaging the target object are provided. The image processing system includes a projector for projecting a projection image having a stripe pattern or a grid pattern toward a target object, and an imager for imaging a target object on which the projection image is projected, and the imager includes an input image obtaining module for obtaining an input image acquired by imaging a target object on which the projection image is projected, a height information calculator for calculating height information of each pixel in the input image by using the input image, and a target object area detector for detecting a target object area where the target object exists in the input image, based on the height information of each pixel in the input image.
