Digital Composting using Chroma
In television and movie industry a so-called "blue box" technology is used, when an object in the foreground (e. g. a person) needs to be placed on a different background (e. g. a computer-generated 3D scene). However, it is often not economically justifiable to build a "blue box", therefore other methods can be used to extract the foreground object and remove or replace bac...
متن کاملAccelerating QDP++/Chroma on GPUs
Extensions to the C++ implementation of the QCD Data Parallel Interface are provided enabling acceleration of expression evaluation on NVIDIA GPUs. Single expressions are off-loaded to the device memory and execution domain leveraging the Portable Expression Template Engine and using Just-in-Time compilation techniques. Memory management is automated by a software implementation of a cache cont...
متن کاملMusic Identification Using Chroma Features
In this paper some specific issues related to Music Information Retrieval (MIR) are presented. First part is dedicated to introductive notions from this field in the field, and second part is dedicated to giving details about the system we built for MusiCLEF 2011. An important aspect related to our work is related to searching metrics able to allow us to identify an audio recording in a databas...
متن کاملChroma Toolbox: Matlab Implementations for Extracting Variants of Chroma-Based Audio Features
Chroma-based audio features, which closely correlate to the aspect of harmony, are a well-established tool in processing and analyzing music data. There are many ways of computing and enhancing chroma features, which results in a large number of chroma variants with different properties. In this paper, we present a chroma toolbox [13], which contains MATLAB implementations for extracting variou...
متن کاملRobust Chroma and Lightness Descriptors
New descriptors for lightness and chroma are presented that are based on properties of a wraparound Gaussian metameric to the given XYZ tristimulus coordinates. For the 1600 samples of the Munsell glossy set, both descriptors are found to correlate to Munsell value and chroma at least as well as the corresponding CIECAM02 descriptors when the Munsell samples are under the CIE C illuminant. Howe...
