Abstract: Methods and apparatuses for intra prediction in video encoding and decoding using a blended intra predictor are described. In one exemplary embodiment, intra prediction is preformed using a blended intra predictor for a pixel of a current block being encoded and decoded. The blended intra predictor is determined by summing with corresponding weights a predictor using the intra prediction direction to be used for the current block and one or more predictors using the one or more corresponding intra prediction directions of the one or more neighboring blocks. The corresponding weights for the one or more neighboring blocks decrease with increased distance of the pixel to the one or more neighboring blocks.

Abstract: A surveying pole is part of a primary surveying system (e.g., a Global Navigation Satellite System (GNSS) or a total station). Cameras are mounted to the surveying pole and used for ground tracking as the survey pole is moved from a place where the primary surveying system is unimpeded to an environment where the primary surveying system is impaired (e.g., to a GNSS-impaired environment or to a position that is blocked from view of the total station). Using ground tracking and/or other sensors, surveying can be continued even though the primary surveying system is impaired.

Abstract: A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks. By this measure, coding procedures performed in tiles—leaf regions—locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision.
