The present application is related to the process of automation of separation by identification, classification and quantification of grains and their possible pertinent materials through equipment that performs such events, aiming at the automation of the whole chain of separation, identification and classification. grain, thus eliminating the human action of the process and thus avoiding errors related to human interaction in the process. This process has 4 steps, as follows: grain and impurities entering the equipment; separation of impurities and grains: grain processing and qualitative and quantitative identification of grains and impurities. The process and equipment can be applied to the separation by identification, classification and quantification of grains such as soybeans, corn, among others, and their possible pertinent materials.

The present disclosure refers to methods and system for classifying rocks according to their minerals from the processing of color images and hyperspectral images. The methods and systems of this disclosure achieve an efficient and low-cost classification of rocks with minerals. In particular, the method uses classification methods that take color images and hyperspectral images and give as a result a probability that the rock or rocks present in said images are suitable or waste.

A cell sorting system that automatically generates a sorting strategy based on examples of target events provided by an operator. The target events can be selected using measurements ranging from traditional flow cytometry measurements to derived measurements that are computationally expensive to complex measurements such as images.

Some embodiments of the methods provided herein relate to sample analysis and particle characterization methods. Some such embodiments include receiving, from a particle analyzer, measurements for a first portion of particles associated with an experiment. Some embodiments also include generating a tree representing groups of related particles based at least in part on the measurements, wherein the tree includes at least three groups. Some embodiments also include generating a measure of relatedness between a first group and a second group of the tree based at least in part on the measurements. Some embodiments also include and configuring the particle analyzer to classify a subsequent particle associated with the experiment with the first group real-time, wherein the subsequent particle is not included in the first portion of particles.

An object of the present invention is to improve the quality level discrimination accuracy of the grain G by a grain quality level discrimination device. The device includes an optical unit 3 that emits light to the grain G, receives reflected and/or transmitted light from the grain G by a photosensor, and obtains information for discrimination of the quality level of the grain G from the upper and lower surface side of the grain G, and a quality level discrimination unit 7 that discriminates the quality level of the grain G on the basis of the information. The information on the upper and lower surface sides can be acquired by one optical unit at the same time so that the divergence therebetween due to the displacement or variation of the attitude of the grain G can be avoided. The reference plate for the correction of the information is placed outside of the moving path of the grain G to prevent it from soiling or damaging. Thus the deterioration of information can be avoided. Further, a reference plate especially for the information to be obtained from the side surface of the grain G may be provided for enhancing the accuracy of the side surface information. Thus the quality level discrimination accuracy can be improved further.
