Estimation of Sow Backfat Thickness Based on Machine Vision.

College of Agricultural Engineering, Shanxi Agricultural University, Taigu 030801, China.
Controlling the backfat thickness of sows within an appropriate range during different production stages helps to increase the number of pigs weaned per sow per year and ultimately enhances the economic benefit to the pig farm. To obtain the backfat thickness of sows automatically, a backfat thickness estimation method based on machine vision is proposed. First, the backfat thickness values and 3D images of the buttocks of 154 Landrace-Yorkshire crossbred sows were obtained using a veterinary ultrasound backfat meter and Azure Kinect DK camera.

An interconnected system employing Kinect Azure and Fitbit Sense for continuous and non-intrusive data collection was used in the PRO-HOME protected discharge program, aiming at monitoring functional and clinical parameters in hospitalized older patients at different risks of frailty. The present study shows the findings on 30 older patients included in the PRO-HOME project. The Fitbit Sense recorded the mean daily and hourly number of steps, mean daily walked distance, and time spent inactive.

Article Synopsis
- The study aimed to create and validate a Kinect-based motion capture system to analyze gait patterns in individuals with shoulder injuries and compare it to a commercial motion capture system.
- The research involved ten participants with shoulder pain, examining their joint movements during walking while using both capture systems simultaneously.
- Results showed that the new Kinect system was mostly comparable to the commercial system, but significant differences were observed in knee flexion-extension and shoulder abduction-adduction, highlighting its potential for clinical use in a cost-effective manner.
A Study on the 3D Reconstruction Strategy of a Sheep Body Based on a Kinect v2 Depth Camera Array.

Non-contact measurement based on the 3D reconstruction of sheep bodies can alleviate the stress response in sheep during manual measurement of body dimensions. However, data collection is easily affected by environmental factors and noise, which is not conducive to practical production needs. To address this issue, this study proposes a non-contact data acquisition system and a 3D point cloud reconstruction method for sheep bodies.

Background: Sarcopenia is a muscle-wasting condition that affects older individuals. It can lead to changes in movement patterns, which can increase the risk of falls and other injuries.
Methods: Older women participants aged ≥65 years who could walk independently were recruited and classified into two groups based on knee extension strength (KES).
