  • Patent number: 9053353
    Abstract: The present invention is directed towards methods for the classification of plant embryos by the application of one or more classification algorithms to analyze digitized images and absorption, transmittance, or reflectance spectra. The methods are generally applicable and emphasize the importance of acquiring and using as much image and absorption, transmittance, or reflectance spectral information as possible, based on objective criteria. The present invention allows automated selection of embryos most suitable for further culture and rejection of those seen as less suitable.

  • Patent number: 9031287
    Abstract: A programmed computer system estimates the age of trees from a number of remotely sensed images of an area of interest. Vegetation Index (V.I.) values are determined for pixel locations in the number of images. The V.I. values are analyzed to find a V.I. value that correlates with a known age of a tree. Once the date of the image that produced the V.I. value is known, the current age of the trees that correspond to the pixel location is determined.
