Unsupervised Approach for Retrieving Shots from Video
Acquiring the video information based on user requirement is an important research, that attracts the attention of most of the researchers today. This paper proposes an unsupervised shot transition detection algorithm using Autoassociative Neural Network (AANN) for retrieving video shots. The work further identifies the type of shot transition, whether abrupt or gradual. Keyframes are extracted...
متن کاملUnsupervised Clustering Algorithm for Video Shots Using Spectral Division
A new unsupervised clustering algorithm, Spectral-division Unsupervised Shot-clustering Algorithm (SUSC), is proposed in this paper. Key-fames are picked out to represent the shots, and color feature of key-frames are extracted to describe video shots. Spherical Gaussian Model (SGM) is constructed for every shot category to form effective descriptions of them. Then Spectral Division (SD) method...
متن کاملa novel unsupervised approach for minimally-invasive video segmentation
background: laparoscopy or minimally invasive surgery is a surgical procedure in which laparoscope and other surgical instruments are inserted inside body via a few small incisions. laparoscope is used to look inside the patient's body and records displayed images. temporal segmentation of laparoscopic videos has many applications like detecting laparoscopic anomalies and interrupts. it is prer...
متن کاملRetrieving Amateur Video from a Small Collection
Research on digital video libraries has been done in extensive and expensive projects (e.g. Open Video Project [1], Físchlár [2], Informedia [3]). Small video collections have small budgets and cannot afford sophisticated techniques to put their material on-line. Though very basic digital video library features can be good enough for enlarging the access to rarely seen material, e.g. folklore f...
متن کاملDirect-from-Video: Unsupervised NRSfM
In this work we describe a novel approach to online dense non-rigid structure from motion. The problem is reformulated, incorporating ideas from visual object tracking, to provide a more general and unified technique, with feedback between the reconstruction and point-tracking algorithms. The resulting algorithm overcomes the limitations of many conventional techniques, such as the need for a r...
