本文采用光栅抽样相位调制密度的假彩色编码技术,对大豆超微结构的电子显微镜黑白图象进行假彩色编码处理。使黑白图象不同灰度赋予不同颜色。通过对彩色图象的分析、初步认定这种假彩色编码对大豆超微结构黑白电镜图象中某些无法辨析的区域具有补偿效应: 彩色图象层次丰富,细微结构清晰可见,具有突出不同空间结构的效应。线粒体的脊膜密度分布在黑白图象中根本无法辨析的灰度接近区域,经彩色编码后,由颜色的变化显出脊膜密度呈不均匀变化。此乃对灰度接近区具有增强其差异,提高辨析能力的补偿效应。下胚轴液胞腔中的物质在黑白图象中肉眼不可见,而彩色图象却明显地显现出来,表明对黑白图象中灰度极弱区具有补偿效应。
In this paper, false color coding of raster sampling phase modulation density was used to process the false-color coded images of the electron microscopy of the soybean ultrastructure. Different colors of black and white images to give different colors. Through the analysis of color images, it is preliminarily determined that this false color coding has a compensating effect on some unidentifiable regions of Soybean ultrastructure black-and-white electron microscopy images: the color images are rich in levels, the fine structures are clearly visible, The effect of structure. Mitochondrial density distribution of the spine in the black and white images can not be resolved in the vicinity of the gray scale, the color coding, the color changes showed uneven changes in the density of the spine. This is a compensatory effect that the gray-scale proximity zone has the advantages of enhancing its difference and improving discrimination ability. Materials in the cell cavity of the hypocotyl fluid are invisible to the naked eye in the black-and-white image, whereas the color image appears conspicuously, indicating a compensatory effect on the grayscale in the black-and-white image.
