ENCODING AND DECODING DEVICE AND METHOD USING INTRA PREDICTION |
摘要 |
The present disclosure relates to encoding and decoding apparatus and method using intra prediction. The encoding apparatus includes a reference pixel characteristics extractor for receiving reference pixel(s) included in neighboring blocks of a target block to encode to determine a reference pixel characteristic and determining whether adaptive filtering is applied to the reference pixel(s), based on reference pixel characteristic; a first intra predictor responsive to when the adaptive filtering is determined by the reference pixel characteristics extractor to be applied for comparing between results of performing intra prediction using high-frequency filtered reference pixel and intra prediction using high-frequency-unfiltered reference pixel to output the cost-efficient result along with filtering information indicating whether to perform filtering; and a second intra predictor for outputting the result of performing the intra prediction using the high-frequency-unfiltered reference pixel when the reference pixel characteristics extractor determines that the adaptive filtering is not to be applied.
