This paper proposes a novel Shift with Importance Sampling (SIS) scheme to improve the efficiency in pedestrian detection but maintain its high accuracy. For fast and efficient object detection, the cascade-Adaboost structure is the commonly-used approach in the literature. However, its detection performance is quite lower due to non-robust features and a fully-scanning on image especially when deformable...
A two-dimensional dam-break flood simulation model using unstructured meshes has been developed to study the hydrodynamics of flooding processes. The model employs the finite volume method to solve the conservation form of the shallow water equations. The HLLC approximate Riemann solver is used for computing the fluxes at cell interfaces because of its easiness to implement and suitability to wet/dry...
Perceived predominant melody of music is the most convenient and memorable description and can be used for content-based music retrieval. However, including human voice and multiple musical instruments playing together, it is difficult to extract a predominant contour of pitches directly from MP3 music recordings. In order to build a similarity music melody model, several audio files, whose melody...
