A general framework for object detection
- Sixth International Conference on
, 1998
"... This paper presents a general trainable framework for object detection in static images of cluttered scenes. The detection technique we develop is based on a wavelet representation of an object class derived from a statistical analysis of the class instances. By learning an object class in terms of ..."

previous approaches, this system learns from examples and does not rely on any a priori (handcrafted) models or motion-based segmentation. The paper also presents a motion-based extension to enhance the performance of the detection algorithm over video sequences. The results presented here suggest
Example-based super-resolution
- IEEE COMPUT. GRAPH. APPL
, 2001
"... The Problem: Pixel representations for images do not have resolution independence. When we zoom into a bitmapped image, we get a blurred image. Figure 1 shows the problem for a teapot image, rich with real-world detail. We know the teapot’s features should remain sharp as we zoom in on them, yet sta ..."

of pixel-based representations is an important task for image-based rendering. Our example-based super-resolution algorithm yields Fig. 1 (h, i). Previous Work: Researchers have long studied image interpolation, although only recently using machine learning or sampling approaches, which offer much power
Machine recognition of human activities: A survey

Video Encoding and Transcoding Using Machine Learning
"... Machine learning has been widely used in video analysis and search applications. In this paper, we describe a non-traditional use of machine learning in video processing – video encoding and transcoding. Video encoding and transcoding are computationally intensive processes and this complexity is in ..."

An MPEG-2 to H.264 Video Transcoder in the Baseline Profile
"... Abstract—Based on our previous efforts, we introduce in this letter a high-efficient MPEG-2 to H.264 transcoder for the baseline profile in the spatial domain. Machine learning tools are used to exploit the correlation between the macroblock (MB) decision of the H.264 video format and the distributi ..."

IMPROVED MACHINE LEARNING TECHNIQUES FOR LOW COMPLEXITY MPEG-2 TO H.264 TRANSCODING USING OPTIMIZED CODECS
"... This paper discusses techniques for efficiently implementing a Mpeg-2 to H.264 video transcoder. The transcoding results reported in the literature are based on a reference implementation and may not reflect the true performance gains obtained in real world systems. We have developed low complexity ..."

"... ABSTRACT This paper presents a novel macroblock mode decision algorithm for inter-frame prediction based on machine learning techniques to be used as part of a very low complexity MPEG-2 to H.264 video transcoder. Since coding mode decisions take up the most resources in video transcoding, a fast m ..."

Reduced Resolution MPEG-2 to H.264 Transcoder
"... This paper describes complexity reduction in MPEG-2 to H.264 transcoding with resolution reduction. The methods developed are applicable to transcoding any DCT based video such as MPEG-2, MPEG-4, and H.263 to the recently standardized H.264 video at a reduced resolution. H.264 is being adopted by mo ..."

allows conversion of MPEG-2 video to the H.264 video format at a reduced resolution with substantially less computing complexity. We use machine learning based approaches to significantly reduce the complexity of this transcoding. Experimental results show a reduction in transcoding time of about 67 % (a

Real-time neuroevolution in the nero video game

Yet if game characters could learn through interacting with the player, behavior could improve as the game is played, keeping it interesting. This pap ..."
