Description
Claims (5)
- 出力フレームの品質を改善するためのビデオ画像処理方法であって、少なくとも、
(1) ビデオ画像が連続画像模式で出力された第1フレームを移動推定処理することにより、第1フレームの連続画像出力のプロセスに含まれたブロック・エレメントの移動ベクトルを取得し、中継フレームを形成するステップと、
(2) 中継フレームに含まれた各ブロック・エレメント毎を移動ベクトルフィルタ処理し、ブロック・エレメント毎を正確な移動ベクトルに調整することにより、ブロック・エフェクトの発生確率を低減させるステップと、
(3) 中継フレームにおいて調整された移動ベクトルの方向が近似したブロック・エレメントを結合し、余分なブロック・エレメントを除去することにより、移動情報のビット数量を低減し、第2フレームの出力を形成するステップと、
を備え、
前記移動ベクトルフィルタ処理は中央値フィルタ(Median filter)方法によってブロック・エレメント毎の移動ベクトルを分析し、
前記中央値フィルタ方法は分析すべきブロック・エレメントの周囲に移動ベクトルが近似した複数のブロック・エレメントに基づき、分析すべきブロック・エレメントに応じた移動ベクトルを見つけ出す
ことを特徴とするビデオ画像処理方法。 - 前記方法は連続画像のフレーム間ウェーブレット(Inter-Frame Wavelet)圧縮作業に適用されることを特徴とする請求項1に記載のビデオ画像処理方法。
- 前記中央値フィルタ方法は殆んどのブロック・エレメントの有した移動ベクトルを見つけ出すことを特徴とする請求項1に記載のビデオ画像処理方法。
- 前記余分なブロック・エレメントを除去するステップは後続の圧縮作業の効率を向上させることを特徴とする請求項1に記載のビデオ画像処理方法。
- 前記余分なブロック・エレメントとは、フィルタ処理された移動ベクトルについてその他のブロック・エレメントとの差異が過大なブロック・エレメントであることを特徴とする請求項1に記載のビデオ画像処理方法。
