IRIT @ TRECVid 2010 : Hidden Markov Models for Context-aware Late Fusion of Multiple Audio Classifiers
نویسنده
چکیده
This notebook paper describes the four runs submitted by IRIT at TRECVid 2010 Semantic Indexing task. The four submitted runs can be described and compared as follows: • Run 4 – late fusion (weighted sum) of multiple audio-only classifiers output • Run 3 – context-aware re-rank of run 4 using hidden Markov model • Run 2 – context-aware late fusion of multiple audio classifiers output with hidden Markov model • Run 1 – late fusion (weighted sum) of multiple audio & video classifiers output

IRIT @ TRECVid HLF 2009 Audio to the Rescue
This notebook paper describes the six runs submitted for the first participation of IRIT at TRECVid 2009 High-Level Feature Extraction task. They were submitted in an attempt to start answering two research questions: 1. Can acoustic information be of any help in this (historically) video-only task? 2. Are Support Vector Machines robust enough to deal with noisy and unbalanced datasets? The six...
متن کاملModeling A-Priori Likelihoods for Angry User Turns with Hidden Markov Models
Current studies dealing with the detection of angry users in automated telephone-based speech applications take acoustic and sometimes linguistic information into account in order to classify the emotional state of the caller in single user turns. Angry user turns, however, don’t appear from nowhere and the likelihood of observing another angry turn rises substantially when anger has already be...
متن کاملEurecom at TRECVid 2007: Extraction of High-level Features
As past years we participated to the high-level feature extraction task and we pursued on the fusion of classifier outputs. New for this year is an experiment with a twodimensional Hidden Markov Model. Altogether we submitted seven runs. Three runs was based on the SVM model, another three was based on the HMM and one run was done by fusing HMM results with the SVM. To compile the runs, color a...

Automatic human Activity Recognition (AR) is an important process for the provision of context-aware services in smart spaces such as voice-controlled smart homes. In this paper, we present an on-line Activities of Daily Living (ADL) recognition method for automatic identification within homes in which multiple sensors, actuators and automation equipment coexist, including audio sensors. Three ...

ion In this paper, we describe our first participation for the semantic indexing task at TRECVID 2010 [1]. We focus on extraction multiple low-level feature sets and a fusion method. In our system, six features are extracted for all the predefined concepts from the keyframes, including global features (RGB color histogram, HSV color histogram, edge histogram, Grey Level Co-occurrence Matrix, GI...
