Description
図1は本実施の形態に係る動画像符号化装置の構成を示すブロック図である。この装置は、例えばテレビ電話やテレビ会議等、画像通信用の携帯または据置型機器に利用できる。また、デジタルVTR、ビデオサーバーなどの画像蓄積および記録装置における動画像符号化装置として利用できる。さらに、この装置における処理の手順は、ソフトウエアまたはDSPのファームウエアの形で実装される動画像符号化プログラムとしても利用できる。
図2のS2に相当する初期分割は分割処理部12において行う。初期分割とは、統合に進む前に行われる分割をいい、分割の合計回数は画像の状態、つまり画像の特徴または特性に依存する。
ついで統合処理部14において、各S0 nについて近傍領域との統合を行う。統合処理部14の内部構成図を図9に示す。同図において、20はラベリング部、21は近傍領域設定部、22は暫定符号化部、23は復号部、24は符号化歪み算出部、25は評価値算出部、26は評価値算出に用いる定数、27は統合判定部、28は統合処理反復指示信号である。
L(Sk n) = D(Sk n) + λR(Sk n) (式1)
1.各領域Sk n自身…L(Sk n)
2.Sk nの近傍領域Ni[Sk n]…L(Ni[Sk n])
3.Sk nとNi[Sk n]を仮に統合した領域…L(Sk n +Ni[Sk n])
の3種類について実施する。ここでNi[Sk n]はSk nの近傍領域を示し、iは複数の近傍領域を区別する番号である。
DL=L(Sk n )+L(Ni[Sk n])−L(Sk n +Ni[Sk n])
が最大となる個所を探し、そのSk nとNi[Sk n]を統合する(S20)。これが第k統合ステージである。この後、統合判定部27はラベリング部20に対して統合処理反復指示信号28を介してラベルの更新を指示する。ラベリング部20は、ラベルl(Ni[Sk n])をラベルl(Sk n)で置き換え、近傍領域設定部21で近傍領域を再設定する。これで新しい領域Sk+1 nと近傍領域Ni[Sk+1 n]が得られ、L(Sk+1 n)、 L(Ni[Sk+1 n])、 L(Sk+1 n +Ni[Sk+1 n])が求まる。統合判定部27は、DLの値が正になる組み合わせがなくなった時点でラベリング部20への指示を停止し、統合処理を終了する(S21)。
Lmc=Dmc+λRmc (式2)
本実施の形態は、実施の形態1の領域分割部2を一部変形した装置に関する。図14は本実施の形態における領域分割部2の内部構成図である。同図のごとく、実施の形態2の領域分割部2は、図3の分割処理部12を均等分割部15に置き換えた形である。この構成において、図15に示すごとく、初期分割処理ではアクティビティの閾値判定を行わず、無条件に領域の最小面積の正方ブロックに均等分割する。最小の領域面積は設定可能としてもよい。
本実施の形態の分割処理では、アクティビティだけでなく、領域の重要度を示す指標(以下、クラスという)も含めて分割の可否を判断する。重要度が高い領域ほど密に符号化されることが望ましく、領域面積は小さくする。重要度が低い領域はできるだけ大きくとり、画素あたりの符号量を削減する。
実施の形態3ではクラス決定に人の注視度を用いた。本実施の形態では画像の特徴量を用いる。本実施の形態では、ある既知の画像の特徴量を保持しておき、それと各領域から算出した特徴量との合致度をもとにクラスを決める。
実施の形態1では、統合処理の際に符号化歪みを考慮した。本実施の形態では、分割処理の段階で符号化歪みを考慮する。
実施の形態1の図9に示した統合処理部14の別の例を説明する。図22は本実施の形態における統合処理部14の内部構成図である。同図において、37は量子化パラメータ設定部、38は量子化パラメータ、39は暫定符号化部である。この統合処理部14の動作は基本的に図10と同じで、S19のみが異なる。
本実施の形態では、実施の形態6のさらに別の例を説明する。図24は本実施の形態の統合処理部14の内部構成図である。同図において、40は動き補償予測コスト算出部、41は動き補償予測コスト、42は暫定符号化部である。
本実施の形態では、いままで述べたいろいろな動画像符号化装置によって生成される符号化ビットストリームを復号する動画像復号装置を説明する。図25に復号装置の構成を示す。同図において、43はビットストリーム解析部、44は領域形状復号部、45は属性情報復号部、46は画像データ復号部、47は動き情報復号部、48は動きパラメータ、49は動き補償部、50は予測画像、51は画像復元部、52は外部メモリ、53は再生画像である。
本実施の形態では、実施の形態1で説明した符号化部7の具体的な一構成例を示すことにする。
本実施の形態では、実施の形態8で説明した画像復号装置における画像データ復号部の具体的な一構成例を示すことにする。
