The MPEG-7 sound-recognition Descriptors and Description Schemes consist of tools for indexing audio media using probabilistic sound models. The Descriptors provide containers for category labels, as well as data structures for quantitative information about sound content. We describe the normative tools, as well as informative methods, for automatic description extraction and sound matching.

The Optical Music Recognition task is more complex than OCR. Despite to the availability of several commercial OMRs: SharpEye2, SmartScore, Photoscore, CapellaScan, etc., none of these is satisfactory in terms of precision and reliability. The efficiency declared by the each distributor is close to 90%, but this value is obtained only when quite regular music sheets are processed and the estima...

Considering the growing recognition of the importance of patient engagement in healthcare decisions, research and delivery systems, it is important to ensure high quality and efficient patient engagement evaluation tools. In this commentary, we will first highlight the definition and importance of patient engagement. Then we discuss the psychometric properties of the patient engagement evaluati...

Nowadays, face recognition technology has been greatly developed; for the problem of low recognition rate in the face recognition system of illumination variation, this thesis proposes the face recognition method of illumination tolerance in two-dimensional subspace based on the optimal correlation filter. Firstly, through the use of a particular class 2D-PCA the face image is reconstructed and...
