DVFX 2003 Video Productions. The Digital Video Special Effects class of Spring 2003 (CS 4480) present their final productions. Students show and discuss the short video segments (less than 1 minutes each) that they have produced to showcase the technical special effects they have generated during the course of the semester. This class is an […]
Award#0205507 – ITR: Analysis of Complex Audio-Visual Events Using Spatially Distributed Sensors ABSTRACT We propose to develop a comprehensive framework for the joint analysis of audio-visual signals obtained from spatially distributed microphones and cameras. We desire solutions to the audio-visual sensing problem that will scale to an arbitrary number of cameras and microphones and can […]
D. Moore and I. Essa (2002). “Recognizing multitasked activities from video using stochastic context-free grammar”, in Proceedings of AAAI 2002. [PDF | Project Site] Abstract In this paper, we present techniques for recognizing com- plex, multitasked activities from video. Visual information like image features and motion appearances, combined with domain-specific information, like object context is […]

Citation [bibtex key= 2002-Schodl-CAVS] Abstract We introduce a new optimization algorithm for video sprites to animate realistic-looking characters. Video sprites are animations created by rearranging recorded video frames of a moving object. Our new technique to find good frame arrangements is based on repeated partial replacements of the sequence. It allows the user to specify […]
Irfan Essa, “Temporal Reasoning from Video to Temporal Synthesis of Video” CMU’s Robotics Institute: Seminar, February 15, 2002 Temporal Reasoning from Video to Temporal Synthesis of Video Abstract In this talk, I will present some ongoing work on extracting spatio-temporal cues from video for both synthesis of novel video sequences, and recognition of complex activities. […]
Depth Layers from Occlusions [bibtex file=IrfanEssaWS.bib key=2001-Schodl-DLFO] Abstract We present a method to extract relative depth information from an uncalibrated monocular video sequence. Our method detects occlusions caused by an object moving in a static scene to infer relative depth relationships between scene parts. Our approach does not rely on any strong assumptions about the […]
