In the open hardware graphics accelerator (ORGFX), there are rectangle, line, triangle and curve rasterization modules. This paper is only focused on the improvement of line rasterization speed. Besides modifying the algorithm itself, hardware implementation and resource consumption are put into consideration here. Originally, ORGFX uses the classic Bresenham line algorithm with high precision and...
Self-labeled training data in semi-supervised learning may contain much noise due to the initial insufficient training data, which may hurt the generalization ability of the final hypothesis. In this paper, we propose an Active Semi-Supervised framework with Data Editing(ASSDE) to improve sparsely labeled text classification. A data editing technique is used to identify and remove noise introduced...
Harmonic distortion is an important analog performance index of the seismic data acquisition system (SDAS). A fast algorithm based on modified FFT pruning is proposed to analyze the harmonic distortion of the SDAS. The key of the harmonic distortion analysis is to compute the fundamental and harmonic components of the measured data. In this paper, a comparative analysis between the algorithm based...
Since recent advances of remote sensing instruments have significantly improved sensor's spectral resolution, pixel resolution is larger than the object size, such that the hyperspectral signal collected by the sensor at each pixel is formed by an integration of signals, which can be considered macroscopically pure, are usually named ldquoendmembersrdquo in hyperspectral image. It is top of all in...
Complex motion makes consecutive frames experience dramatic change, and thus becomes a barrier to object-tracking. Three factors contribute to more complexity of motion: longer sampling period,an moving object with complex appearance and nonrestraint movement, occlusion, which causes mean shift algorithm losing its target due to too low a Bhattacharyya coefficient. To treat it, mean shift algorithm...
