Pixel-adaptive interpolation algorithm for image upscaling
Methods and apparatuses use a pixel-adaptive interpolation algorithm to provide image upscaling. For each pixel location, the algorithm determines whether to use a high quality scaler algorithm (such as a polyphase filter, for example) or a directional interpolator to determine the pixel value.

Methods and apparatus for geometric-based intra prediction
Methods and apparatus are provided for geometric-based intra prediction. An apparatus includes a video encoder for encoding picture data for at least a portion of a block in a picture by detecting a local geometric pattern in a surrounding area with respect to the portion, and performing at least one of interpolation and extrapolation with respect to an edge direction of the local geometric pattern to generate an intra prediction for the portion..

Inter picture prediction method for video coding and decoding and codec
The invention discloses an inter picture prediction method for video coding and decoding and a codec. The inter picture prediction method for video coding comprises: performing motion estimation over integer pixel positions of a reference picture, to determine an optimal motion vector for a current prediction unit in a current picture; and performing interpolation filtering processing for motion estimation over fractional pixel position by using the integer pixel position information to which the optimal motion vector directs in the reference picture, and spatially neighboring pixel information of the current prediction unit in the current picture.

Satellite tracking system and method of controlling the same
A satellite tracking system and a method of controlling the same, in which the satellite tracking system comprises an argo-m operation system (aos) and a tracking mount system (tms). The aos comprises a time & frequency system configured to include a global positioning system (gps) receiver, and to receive universal time coordinated (utc), and an interface control system (ics) configured to calculate the orbital position data of a satellite using the utc and per-satellite estimated orbit data by means of lagrangian interpolation, and to send a command to track the position of the satellite.
