This paper studies a new type of solar spectral fitting technique based on LED. Firstly, Using the light collecting equipment collected several typical periods of the solar spectrum of Beijing. And then, After a preliminary analysis, five specific bands LEDs are used to fit the target solar spectrum. Among them, the use of two pieces of normal white light LEDs, a single LED with 480nm wavelength,...
Moving object detection is usually used in gray image, and the color image should be converted to gray images to achieve detection. However, the color object can't be described by simple gray information completely. In order to achieve automatic color moving object detection, the method based on automatic color clustering is especially proposed. Because the difference between adjacent pixels in an...
Depth map super resolution from multi-view depth or color images has long been explored. Multi-view stereo methods produce fine details at texture areas, and depth recordings would compensate when stereo doesn't work, e.g. at non-texture regions. However, resolution of depth maps from depth sensors are rather low. Our objective is to produce a high-res depth map by fusing different sensors from multiple...
The shadows of moving objects have great influence on the accuracy and effectiveness of objects tracking and behavior recognition, this paper proposes an elimination method based on Gaussian Mixture Model (GMM). First, we improve the adaptability of GMM by making learning rate change with the speed of the moving object to eliminate ghost. Then, we come up with a shadow elimination method based on...
With the aim of solving the problems of the Petri nets to the place/transition nets automatic conversion and realization of Petri nets parallel control and running, the algorithm is proposed to transform Color Petri net systems transform into P/T nets. The algebraic model of colored Petri nets and P/T nets, and its intrinsic mechanism is analyzed, the process and theory verification of the colored...
Segmentation of Immunohistochemical image plays an import part in quantitative assessment of immunohistochemical image. In this paper, an automatic segmentation method was proposed according to characteristics of color immunohistochemical images based on YUV color space. First, it extracts Y, U, V three-component diagram and then we discover that positive cells are distributed in the high gray areas...
Immunohistochemical color image segmentation has important application value for quantitative assessment of immunohistochemical image. In this paper, an automatic segmentation method was proposed according to characteristics of color immunohistochemical images. First of all, we established a Chromatics criteria in RGB space so that positive cells regional and negative cells region were separated automatically...
In order to improve the drying qualities of aquatic product, reduce the energy consumption, a new drying technology with electrohydrodynamic (EHD) was put forward for scallop muscle in the paper. The scallop muscle, as a representative of aquatic product, were dried in a high voltage electric drier at 15degC, as well as in a oven at 60degC and ambient air respectively, and the energy consumption of...
Taking Asian-Pacific robot contest as the background and robot vision system as the object of research, the target recognition arithmetic based on color information is introduced. It proposed eight connection clustering arithmetic based on color double thresholds in HSI color space. H-S double threshold is discussed deeply and pixels classed based on table is used, so calculating of image segmentation...
In order to improve the drying qualities of seaweed, a new drying technology with the high voltage electric field was put forward for seaweed in the paper. The kelp were dried under a direct current (DC) high voltage electric field (HVEF) using a multiple point electrode and a grounded rectangle stainless steel plate at 15degC. The results indicate that the high voltage electric field can improve...
Rapid restoration is vital for power system restoration to mitigate the consequences of major blackout. However, conventional textual restoration procedure hides the relations between conditions and the restoration actions, tends to slow down the restoration process and make the restoration harder. This paper proposed a visualization and support tool of restoration process with Hierarchical CPN (Color...
