  2. Crop coefficient - Wikipedia

    en.wikipedia.org/wiki/Crop_coefficient

    Crop coefficients are properties of plants used in predicting evapotranspiration (ET). The most basic crop coefficient, K c , is simply the ratio of ET observed for the crop studied over that observed for the well calibrated reference crop under the same conditions.

  3. Cropping (image) - Wikipedia

    en.wikipedia.org/wiki/Cropping_(image)

    Cropping is the removal of unwanted outer areas from a photographic or illustrated image. The process usually consists of the removal of some of the peripheral areas of an image to remove extraneous visual data from the picture, improve its framing, change the aspect ratio, or accentuate or isolate the subject matter from its background.

  4. Plant growth analysis - Wikipedia

    en.wikipedia.org/wiki/Plant_growth_analysis

    Agronomic studies often focus on the above-ground part of plant biomass, and consider crop growth rates rather than individual plant growth rates. Nonetheless there is a strong corollary between the two approaches. More specifically, the ULR as discussed above shows up in crop growth analysis as well, as: = . = .

  5. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    A major function is as a constituent of cell walls. When coupled with certain acidic compounds of the jelly-like pectins of the middle lamella, calcium forms an insoluble salt. It is also intimately involved in meristems , and is particularly important in root development, with roles in cell division, cell elongation, and the detoxification of ...

  6. Image editing - Wikipedia

    en.wikipedia.org/wiki/Image_editing

    Digital editors are used to crop images. Cropping creates a new image by selecting a desired rectangular portion from the image being cropped. The unwanted part of the image is discarded. Image cropping does not reduce the resolution of the area cropped. Best results are obtained when the original image has a high resolution.

  7. Crop factor - Wikipedia

    en.wikipedia.org/wiki/Crop_factor

    The most commonly used definition of crop factor is the ratio of a 35 mm frame's diagonal (43.3 mm) to the diagonal of the image sensor in question; that is, = /. Given the same 3:2 aspect ratio as 35mm's 36 mm × 24 mm area, this is equivalent to the ratio of heights or ratio of widths; the ratio of sensor areas is the square of the crop factor.

  8. Comparison gallery of image scaling algorithms - Wikipedia

    en.wikipedia.org/wiki/Comparison_gallery_of...

    An adaptable technique which can deliver variable amounts of detail or smoothness. It aims to preserve the shape and coordinates of original details, without blurring those details into neighboring ones. It will avoid blending pixels which directly touch each other, and instead only blend pixels with their diagonal neighbors.

  9. Lasso tool - Wikipedia

    en.wikipedia.org/wiki/Lasso_tool

    The lasso (or "free form selection") is an editing tool available, with minor variations, in most digital image editing software [1] and some specific strategy games.It is often accessed from the standard main menu (in Photoshop, [2] Paint Tool SAI, [3] and GIMP, [4] as common examples), by clicking the icon of a dotted line shaped like a rope lasso, from which the common name arises.
