AB  - To obtain effective features applicable to hand morphology recognition, the method of obtaining effective feature
indicators based on the Random Forest (RF) algorithm to downscale hand morphology parameters is proposed. Firstly,
232 female university students collected three-dimensional hand information, constructed auxiliary point, line, and
surface standardised measurement methods, obtained 33 characteristic parts of human dimensions, and used k-means
clustering for hand morphology subdivision. Hand morphology can be divided into three categories: short, slender and
broad. The RF algorithm is used for feature index importance assessment and hand shape recognition model. The
accuracy of the feature metrics determined by the RF algorithm, PCA, and VC method applied to hand shape recognition
is compared and analysed to verify the effectiveness of the dimensionality reduction of the RF algorithm. The results
showed that the feature indexes used for hand shape recognition were five items: hand length, thickness at the
metacarpal, thenar width, the distance between the thumb and index finger, and distance from the root of the little finger
to the centre of the wrist. Using the RF algorithm to reduce the dimensionality is more effective; the average recognition
accuracy of the four hand shape recognition models is 93.78% on average, compared with PCA and VC reduction
methods, the average accuracy of hand shape recognition models is increased by 19.17%, and 14.86% respectively.
The study's results can provide methodological references for the objective selection of characteristic indicators and
morphological recognition of human body parts.
