High Frame-Rate Television
The frame and field rates that have been used for television since the 1930s cause problems for motion portrayal, which are increasingly evident on the large, high-resolution television displays that are now common. In this paper we report on a programme of experimental work that successfully demonstrated the advantages of higher frame rate capture and display as a means of improving the qualit...
متن کاملMotion Compensated Frame Rate Up-Conversion for Low Frame Rate Video
Frame rate up-conversion is useful for low frame rate pictures such as movie. In case of conversion, basic motion compensation causes gap at covered area and uncovered area. To avoid the gap, we propose the motion compensation centered at the position of target. Fully motion compensated interpolation is possible in this method. To realize this, error normalizing by block activity is used for mo...
متن کاملConfidence-based adaptive frame rate up-conversion
In this article, we propose a new frame rate up-conversion (FRU) method for temporal quality enhancement. The proposed FRU algorithm employs gradual and adaptive motion estimation based on confidence priority for selecting more accurate motion vectors (MVs). In order to estimate accurate MVs, we adaptively alternate a search range and the order of blocks to be searched depending on the confiden...
متن کاملStatistical sequence-to-frame mapping techniques for voice conversion
あらまし 話者変換の目的はある話者の声を別の話者の声に変換することである。これは二つの話者区間において音 声時系列のマッピング関数を求めることとして考えられる。GMMを用いた統計的マッピング方法 [1], [2]は話者変換 のタスクにおいてよく使われている。ただし、GMMを用いた変換技術はフレームからフレームへのマッピング関数を 使用しているので、音声時系列のコンテキスト情報が十分には使われていない。HMMは音声時系列の有効なモデル であり、音声認識や音声合成においてよく使われている。本研究は HMMを用いた音声変換を研究対象とする。我々 は HMMを用いた回帰、シーケンスからフレームの変換関数を導出した。先行の HMMを用いた音声変換方法 [3]~ [5]は強制切り出し (forced alignment)によって音声を分割し、各区間に対して変換を行う。それらの方法と異なって, 我...
متن کاملNovel fast motion estimation for frame rate/structure conversion
Different multimedia applications and transmission channels require different resolution, frame rates/structures and bitrate, there is often a need to transcode the stored compressed video to suit the needs of these various applications. This paper is concerned about fast motion estimation for frame rate/structure conversion. In this paper, we proposed several novel l algorithms that exploit th...
