Method and apparatus for intra-prediction in a video encoder

Apparatus for intra-prediction for a group of samples in an image being coded, comprising:

• an encoder configured to code the group of samples using a candidate group of samples as a predictor;
• a temporal/spatial prediction module, within the encoder, configured to:
• define a target template for the group of samples;
• compare the target template with affine transformations of candidate templates within a search area of the image;
• identify at least one matching template of the candidate templates as matching the target template;
• determine the candidate group of samples based on the at least one matching template.
