In this paper, I use the NVIDIA CUDA technology to perform the chroma key algorithm on stereoscopic images. NVIDIA CUDA allows to process parallel algorithms on GPU. Input data are stereoscopic images with the monochromatic background and the destination background image. Output data is the combination of inputs by using the chroma key. I compare the algorithm efficiency between the GPU and CPU...

This paper presents our submission to the MIREX 2008 Audio Chord Detection task. The front-end of our system incorporates a novel feature extractor which uses multiple pitch tracking techniques to extract for each frame a chroma profile that is more robust against chroma contributions not originating from fundamental frequencies but from harmonics thereof. The back-end of our system implements ...

This extended abstract details a submission to the Music Information Retrieval Evaluation eXchange (MIREX) 2011 for the “Audio Key Detection” task. The system named ircamkeymode performs key (C, Db, D, E, ...) and mode (Major, minor) detection. The system is a simplified version of the systems described in [6] [5]. We briefly summarized it below. 1. OVERVIEW OF THE MODEL 1.1 Chromagram extracti...

It is well known that noise cleaning a full-color image, as if it were a set of independent single-channel images, produces suboptimal results. Instead, it is generally recognized that transforming a color image into a luminance-chrominance space permits the use of simple and aggressive chrominance noise-cleaning operations that minimize degradation of luminance information. These chrominance n...

Transformations of natural images in the perulated with respect to luminance and chromaticity in order ceptually uniform CIELUV color space have been investito improve the display of color. Usually, some implicit gated with respect to perceptual image quality. To this assumptions are made to limit the almost infinite number end, digitized color images of four natural scenes were of possible man...

Musicians recognize pitch as having two dimensions. On the keyboard, these are illustrated by the octave and the cycle of notes within the octave. In perception, these dimensions are referred to as pitch height and pitch chroma, respectively. Pitch chroma provides a basis for presenting acoustic patterns (melodies) that do not depend on the particular sound source. In contrast, pitch height pro...
