The extraction and recognition of veterinary B-ultrasound diagnostic information focuses on extraction and recognition. It mainly includes edge detection, three-dimensional reconstruction, texture recognition, automatic tracking detection of cardiac image signals, computer storage and management of veterinary B-ultrasound images, etc.

In veterinary B-ultrasound images, edges can be used to describe the boundaries of different biological tissues and the range of various organ lesion areas, and can also be used as the contours of moving organs such as the heart and ventricles to describe their movement processes. Because veterinary B-ultrasound images are relatively rough, especially in the early stages of lesions of some organs, the edges of veterinary B-ultrasound images are relatively fuzzy and difficult to detect, so better edge detection technology is needed.

Three-dimensional reconstruction is to process two-dimensional veterinary B-ultrasound images into three-dimensional stereo images. It includes the reconstruction of the three-dimensional shape of organs and the three-dimensional processing of veterinary B-ultrasound section images about grayscale. For the reconstruction of the three-dimensional shape of organs, there must be a sufficient number of two-dimensional veterinary B-ultrasound images with different cross sections. These two-dimensional veterinary B-ultrasound images of different cross sections can be obtained by moving the position of the probe on the human body and keeping the angle of the veterinary B-ultrasound probe to the body unchanged, or by keeping the position of the veterinary B-ultrasound probe unchanged, but rotating the probe around its axis.

Texture recognition is the analysis and identification of various areas of different echo spatial distribution under similar total grayscale conditions. At present, the extraction of veterinary B-ultrasound image information is no longer limited to the recognition of organ contours, but has begun to be interested in whether the tissue is normal or not. Since the basis of veterinary B-ultrasound diagnosis is based on the principle that abnormal changes in the microstructure of the tissue will be reflected in the acoustic characteristics of the tissue, the normality of the animal body tissue is reflected in the veterinary B-ultrasound image as the texture characteristics of the tissue part.
