1.Why is the bioproduction robot necessary? Answer： (1)?Although many agricultural operations have been mechanized, there are still many treacherous, laborious，and monotonous tasks that are not suited for human beings，but require certain human like intelligence to perform； (2)?The availability of the farming workforce is decreasing at an alarming rate in many countries．Compared With many other industries, agriculture is less attractive for the younger generation，as indicated by recent trends．This means that the supply of human resources for farming will continue to decrease in the foreseeable future．The development of bioproduction robots，especially the kind with expert knowledge，can serve to preserve some farming expertise； (3)?The problem of labor shortage frequently results in rising labor costs，if the production is to continue； (4)?The market demand for product quality has become an important factor in bioproduction．Quality evaluation of products has relied mainly on human judgment. 2.How to analysis the colors feature of a fruit? Answer：(1) Open a fruit image.(2)Split the fruit image into R, G and B component (or Chromaticity) images.(3) Chose one of the R, G and B component images, and make the fruit area as ROI.(4) Calculate the R and G component histogram of the ROIs, and get t he R component mean value and the G component mean value of the fruit.(5) Use x=R/(R+G+B) and y=G/(R+G+B) the get the x-y coordinate value (x, y).(6) Plot (x,y) on the x-y coordinate graph. 3.How to locate the defect area on the image of a tomato? Answer：1) Open the tomato image.2) Split the tomato image into R, G and B component images.3) Chose one of the R, G and B component images, using Sobel operator to get an edge image.4) Binarize one of the R, G and B component images to a binary image.5) To make the edge image and binary image using an operator, and then get the defect area of the tomato. 4.What color expression methods is used in a machine vision syste
