چکیده

Automatic identification of special effects is a prerequisite for video indexing and intelligent video encoding. In this paper we present an algorithm for fade and dissolve scene change detection in video sequences. We use statistical features of the images to identify these special effects in uncompressed video. DC-estimation [4] is used to evaluate statistical features both in H.263 [lo] and MPEG-2 [ 1 I] compressed video. Results show that these special effects can be identified accurately with the proposed scheme.

Fade-in and fade-out detection in video sequences using histograms

There is an increased need to extract key information automatically from video for the purposes of indexing, fast retrieval, and scene analysis. To support this vision, reliable scene change detection algorithms must be developed. Several algorithms have been proposed for both sudden and gradual scene change detection in uncompressed and compressed video [I-81. In this paper we present an algor...

Tham 15 . 8 Fade , Dissolve and Wipe Production in Mpeg - 2 Compressed Video

With the increase of digital technology in video production, several types of complex video special efsects editing have begun to appear in video clips. In this paper, a novel algorithm is proposed for fade-in, fade-out, dissolve and wipe video editing operations in MPEG-2 [ I ] compressed domain without fu l l frame decompression and motion reestimation. Results show that both objective and su...

MSR-Asia at TREC-10 Video Track: Shot Boundary Detection Task

The video track is added into TREC-10, composed of two tasks, automatic shot boundary detection and video retrieval. In this year, we (MSR-Asia) participated in the video track, focusing on shot boundary detection task. Our work is to find out all of boundaries the shot changes by a fast algorithm based on uncompressed domain. In our algorithm, all of non-cut transitions are considered as gradu...

Improved Fade and Dissolve Detection for Reliable Video Segmentation

We present improved algorithms for automatic fade and dissolve detection in digital video analysis. We devise new two-step algorithms for fade and dissolve detection and introduce a method for eliminating false positives from a list of detected candidate transitions. In our detailed study of these gradual shot transitions, our objective has been to accurately classify the type of transitions (f...

Compressed Domain Scene Change Detection Based on Transform Units Distribution in High Efficiency Video Coding Standard

Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...
