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.

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.

A method for controlling a multisource illumination device in gated optical system is provided. A plurality of light sources is divided into groups, and wherein each group is characterized by a respective radial distance from a primary optical axis. Therein, the dimming level of a group is controlled independently from the dimming level of other groups based on the radial distance of the group from the primary optical axis.

A user interface adaptation module identifies a dominant color of a portion selection of a frame of a video and, based on the dominant color, generates colors for components of a user interface in which the video is displayed. The colors of the user interface components are set based upon the generated colors and upon context information such as a playing state of the video. The setting of the component colors in this way allows the user interface to adjust to complement both the played content of the video and the video's context. In one embodiment, the dominant color is identified by partitioning individual pixels of the portion selection based on their respective colors. In one embodiment, a set of primary color variants is generated based on the dominant color, and different colors are generated for each type of user interface component based on the different primary color variants.
