A Review of Morphometric Measurements Techniques on Animals Using Digital Image Processing

Abstract

The existence of livestock, especially beef cattle in Indonesia, has enormous potential. In 2018, the population of beef cattle in Indonesia reached 16,432,945 heads. This population continues to increase in 2019 to 17,118,650 individuals. The increase in livestock productivity can be assessed from the dimensions of the body of the livestock by measuring directly using measuring instruments. This technique is called morphometrics. Morphometrics is a quantitative analysis technique (body dimensions) that includes shape and size. Morphometric data is an important parameter used to study livestock anatomy, productivity, growth rate, and performance quality of livestock. Manual measurements can provide several obstacles, including causing livestock to be stressed more easily, measurements become less accurate because cattle move too much and can even pose a risk of livestock aggressiveness that causes people to be injured by livestock attacks. This review article aims to summarize the literature related to morphometric techniques in animals in terms of the measurement approach used and the objects measured. Writing review articles are done by summarizing and analyze the morphometric measurement process approach technique. The articles studied were obtained by searching in international and national journals at Springer, ScienceDirect, IEEE, etc. The search was carried out with the keywords "Morphometrics", "Morphometrics", "Zoometric", and "Digital Image Analysis". The conclusion drawn from the review is that there are still many things that can be developed in this morphometric measurement technique. The key to the success of developing this morphometric technique method is that the more effective and efficient the measurement technique is, the better the results will be obtained. The final result expected in the future is to be able to create a morphometric approach technique that can be used in all fields and animals. Able to produce accurate and efficient morphometric measurements.
