Ultrasonic image fusion using compressed sensing

Presented is a new approach to fuse the fundamental ultrasonic image and second-harmonic ultrasonic image using compressed sensing. First, source image compressed measurements are obtained by starshaped sampling mode in the 2D Fourier plane. The measurements are fused into fused measurements by the adaptive weighted average fusion scheme. The fused image is then reconstructed from the fused measurements by total variation optimisation. Experimental results show that the proposed method has better performance over wavelets and principal component fusion methods in improving the quality of the fused image.
