In this topic, basic tools for a complete image analysis chain are introduced. These include, in order, image preprocessing (image enhancement or restoration, usually by filtering), image segmentation, some post segmentation enhancement, and finally, quantitative analysis. One very typical example was presented by de Reuille et al.,5 who acquired confocal sections of the shoot apical […]
In previous topics the image was introduced as a spatial arrangement of discrete values: image values that represent a physical metric. Neighboring pixels relate to each other in a defined spatial relationship. The human eye is very adept at recognizing spatial relationships, such as repeat patterns, irregularities (noise), edges, or contiguous features. For image processing […]
