Abstract
The liquid turbidity detection is easily affected by the noise
So a Robert operator edge detection algorithm based on Bidimensional Empirical Mode Decomposition(BEMD) to detect medical liquid opacity is proposed
which divides the medical liquid images into Intrinsic Mode Function(IMF)by using BEMD.Then we employ a Robert operator to detect the edge of each IMF.The image edge is rebuilt layer by layer selectively.Such process can highlight the edge details of the image and impurities.
