Latest Patents

One of Guibin Lu's latest patents is titled "Rapid selection method for video intra prediction mode and apparatus thereof." This application discloses methods and apparatuses for intra prediction mode selection. The method involves acquiring a gradient amplitude and a gradient angle of each element in a prediction block. It analyzes statistics on the gradient angles and generates a gradient angle histogram of the prediction block. If the texture smoothness of the prediction block is greater than a first pre-determined threshold value, it determines that the prediction block is a first-type prediction block. The prediction mode of the first-type prediction block is set to include a direct current prediction mode and a planar prediction mode. Conversely, if the texture smoothness is less than a second pre-determined threshold value, it identifies the prediction block as a second-type prediction block, setting an angular prediction mode based on the maximum peak value in the gradient angle histogram.

Another notable patent is "Method, apparatus and coder for selecting optimal reference frame in HEVC coding." This invention includes a method, an apparatus, and a coder for selecting an optimal reference frame in HEVC coding. The method involves obtaining optimal reference frames of prediction units spatially adjacent to a current prediction unit. It determines the optimal reference frame of the current prediction unit based on the correlation between optimal reference frames of the spatially adjacent prediction units in the same layer depth. This approach eliminates the need for ergodic rate distortion cost calculations for the prediction units of minimum layer depth, thereby enhancing coding efficiency.
