Some imaging strategies in multi-angle spatial compounding

Multi-angle compound images were generated with four schemes: mean, median, root-mean-square and geometric mean. The in vitro images, based on formalin fixed porcine tissue, were analyzed by visual inspection and by calculation of speckle contrast and contrast between different tissues. The mean and rms images featured the largest enhancement of distributed specular reflections. The median image appears somewhat noisy. However, the quantitative analysis did not indicate large differences between the images.
