WebThe proposed VPN uses two sub-VPN architectures in cascade to predict the current frame in the same time instance. The VRF is expected to have higher temporal correlation than a conventional reference frame, and, thus it is substituted for a conventional reference frame. The proposed technique is incorporated into the HEVC inter-coding framework.

WebNov 1, 2024 · We presented a gated fusion-guided framework in our model design, which effectively combines the inter–intra frame local and temporal feature heterogeneity. Our decoupled model includes a modified loss function to constrain the pixel errors and incorporates the intermediate convolution feature maps through skip connections. WebApr 11, 2024 · The prediction angle is calculated as the following: Prediction angle = nominal_angle + (angle_delta * angle_step), Table 6. Finer of Intra Mode norminal_angle is determined by the prediction mode, and is the same as VP9; angle_delta is in a predefined range and angle_step is a predefined value.
Webthe latest H.265/HEVC, are all based on the frame of the hybrid encoding. Prediction encoding is one of the core technologies that influences the compression performance. It can be divided into inter-frame prediction encoding and intra-frame prediction. Inter-frame prediction creates a prediction model from one or more previously encoded
