Abstract: A field image is formed using a tristimulus color model and used to detect target plants or entities on a field. Through the use of a luminance parameter floor, hue and saturation selection steps, feature recognition, a sizing floor and an aspect ratio ceiling, a very fast way is devised to recognize a target plant without need for consulting plant attribute databases, or to analyze spectral or other specialized data for comparison with known attributes. This allows a low calculational processing load and use of simple hardware such as a single board computer to handle machine vision in real time. Treatment steps can include a spray event, a light treatment, and a thermal/mechanical trauma.

Abstract: The purpose of the present disclosure is to provide a small optical integrator for increasing color mixing property and homogeneity. An optical integrator is provided with a light entrance surface and exit surface (002, 003), and side surfaces (004, 005, 006, 007) that connect the entrance surface and the exit surface, and is internally filled with a light guide material having a refractive index. The light guide material contains scattering particles for scattering light that have a refractive index different from the refractive index of the light guide material. The light that has entered via the entrance surface propagates from the entrance surface side toward the exit surface while being scattered by the scattering particles in the light guide material, wherein part of the scattered light is guided to the exit surface by propagating while being confined, by internal reflection on the side surfaces, in the light detector.

Abstract: A system and method for performing Bayer reconstruction of images using a programmable graphics processing unit (GPU) are described herein. A Bayer filtered image in RAW format is uploaded to the GPU, unpacked, and reconstructed. Optionally, the reconstructed image may be transformed into any desired color space and/or displayed by a video card in which the GPU resides. The reconstruction is performed independently on each of the red, blue, and green image fields. The red and blue image fields are reconstructed using first and second interpolation passes in first and second orthogonal directions. Each reconstruction pass preferably employs a two-lobed Lanczos filter. The green image field is interpolated using a single interpolation pass in a direction diagonal to the first and second orthogonal directions, and preferably employs a box filter.

The system further includes a processing circuit configured to generate a disparity map of the object, detect a first boundary of the object in the disparity map, identify a shadow region in the disparity map adjoining the first boundary, the shadow region including pixels with codeword outages, and change a shape of the object in the disparity map based on the detected shadow region. The system further includes a memory device configured to store the disparity map.
