TL;DR: In this paper, the authors proposed a method and equipment for capturing abstract images, and relates to a photographing method, which comprises the following steps: according to the physical characteristics of light, projecting luminescent images on a screen onto one or more than one image conversion plates.
Abstract: The invention provides a method and equipment for capturing abstract images, and relates to a photographing method. The method comprises the following steps: according to the physical characteristics of light, projecting luminescent images on a screen onto one or more than one image conversion plates, wherein, the image conversion plates are placed in the front of the screen and can cause the diffuse reflection, interference, refraction or diffraction of light so that the distortion and unreality of the original images are generated to form the abstract images; and then capturing the abstract images from the image conversion plates by utilizing a common camera. The image conversion plates are made from materials such as plastics, glass and the like, thus being cheap and available; and the illuminated surfaces of the plates are uneven, and the plates can be provided with film bubbles and penetrable small holes or slits. By utilizing the method and the equipment, colorful and available captured object resources can be provided for capturing the abstract images, thus the method is simple, economical and practical.

TL;DR: In this article, the NIR image was considered more effective in separating the soil background for its higher contrast value and was selected for image processing to calculate the leaf area index (LAI).
Abstract: Leaf Area Index (LAI), as a fundamental parameter to evaluate the physiological condition of plants, was calculated by image processing based on machine vision technology. The measurement system hardware consisted primarily of the MS3100 3CCD camera, the image grabber card, a desktop computer and the acquired images were processed by Matlab and ENVI. After acquiring the 3 images by the 3CCD camera of Green, Red and NIR channels, the NIR image was considered more effective in separating the soil background for its higher contrast value. Thus, it was selected for image processing to calculate the leaf area index (LAI). The transect method was applied to obtain the threshold 50 in the binary image conversion and the soil background was thus eliminated as a result that most of its reflectance in the image was under 50. Then the 'imerode'-'imdilate' operation in the image processing box of Matlab was used to remove the left crop stem noises, including those small weeds in the binary image background. Consequently, the LAI of the acquired NIR image was calculated as 0.523 by dividing the total image pixel amount by that of the black pixels in the binary image.
