Shot Boundary Detection with Simple Boosted Classifiers
نویسندگان
چکیده
This paper presents an approach to detection of hard cuts in video based on simple boosted classifiers and a large set of intra-frame distance measures, which are extracted from pairs of images in small local neighborhood. The performance of the proposed approach is evaluated on the test data from TRECVID 2007 shot boundary detection task.

Empirical Analysis of Detection Cascades of Boosted Classifiers for Rapid Object Detection
Recently Viola et al. have introduced a rapid object detection scheme based on a boosted cascade of simple feature classifiers. In this paper we introduce and empirically analysis two extensions to their approach: Firstly, a novel set of rotated haar-like features is introduced. These novel features significantly enrich the simple features of [6] and can also be calculated efficiently. With the...
متن کاملA Cascade of Boosted Generative and Discriminative Classifiers for Vehicle Detection
We present an algorithm for the on-board vision vehicle detection problem using a cascade of boosted classifiers. Three families of features are compared: the rectangular filters (Haar-like features), the histograms of oriented gradient (HoG), and their combination (a concatenation of the two preceding features). A comparative study of the results of the generative (HoG features), discriminativ...
متن کاملBoosted Detection of Objects and Attributes
We present a new framework for detection of object and attributes in images based on boosted combination of primitive classifiers. The framework directly minimizes the detection error by learning a set of simple, computationally efficient threshold-based detectors. We apply this framework to segmentation of human skin and detection of faces in images. We show that despite its simplicity the met...
متن کاملVision-Based Detection and Distance Estimation of Micro Unmanned Aerial Vehicles
Detection and distance estimation of micro unmanned aerial vehicles (mUAVs) is crucial for (i) the detection of intruder mUAVs in protected environments; (ii) sense and avoid purposes on mUAVs or on other aerial vehicles and (iii) multi-mUAV control scenarios, such as environmental monitoring, surveillance and exploration. In this article, we evaluate vision algorithms as alternatives for detec...
