RESEARCH ON OPTIMIZATION OF IMAGE FAST FEATURE POINT MATCHING ALGORITHM

Abstract The author studied the feature point Canine - Clothing - Coats extraction and matching based on BRISK and ORB algorithms, experimented with the advantages of both algorithms, and ascertained optimal pyramid layer and inter-layer scale parameters used in features extraction and matching for the same scale image and different scale images wi

Pain causes altered arousal and specific behaviours that are rare at other times (pain indicators).We examined whether beef cows (mean age 6 years) are sensitive to pain indicators in addition to arousal following ear tagging and rubber ring castration (males only, n = 31) of their calf (n = 58).Behavioural pain indicators and activity were recorde
