Primary Institution: University of Saskatchewan
Hypothesis
Bovine CL boundaries could be located within 1–2 mm by a level set image segmentation methodology.
Conclusion
The technique is promising for accurately locating CL boundaries, although some deviations can occur.
Supporting Evidence
- The mean absolute distance (MAD) was 0.87 mm, indicating good accuracy.
- Mean sensitivity was 0.814, showing the method often under-segments CLs.
- Mean specificity was 0.990, indicating high accuracy in identifying non-CL regions.
Takeaway
This study shows a way to find the edges of a part of a cow's ovary using special computer techniques on ultrasound pictures.
Methodology
The study used level set methods to segment CL boundaries from ultrasound images, comparing results to manually delineated ground truth.
Limitations
The method may under-segment CLs and is sensitive to image noise.
Participant Demographics
Images were obtained from the ovaries of heifers.
