基于GPU的彩色显微光学图像快速三维可视化
GPU-BASED 3D VISUALISATION OF COLOURFUL MICROSCOPIC OPTICAL IMAGE
摘要
Abstract
The computation of 3D visualisation for colour microscopic optical images is relatively large.The visualising scheme based on CPU single-thread serial computation cannot satisfy the requirement of real-time display.This paper proposes a GPU-based fast 3D visualisation algorithm of colour microscopic optical images.The method utilises the function of maximum intensity projection (MIP)to realise visualisation.By using interpolation calculation to calculate the RGB values of the equal-interval points on the light through the object,it chooses the RGB value of the point with maximum brightness as the colour value of the corresponding pixel of light.The above-mentioned process is completed by multi-thread execution through the built kernel function on GPU.Finally,the projection image is sketched directly by OpenGL.The colour image of mice’s kidney cells and multi-layer cell samples pictured by confocal laser scanning microscopy are employed to validate this algorithm.Experimental result turns out that:compared with the visualisation means based on CPU single-thread serial computation,on the condition of the same performance on displaying quality,the GPU-based visualisation method accelerates the computation speed by 90 times.This method significantly improves the performance of real-time display during microscopic image processing.关键词
