There is a strong need for acquisition of high quality volume data sets, with the vision of visualizing organs, engines or other materials for variant fields. Visualized computer model provides interactive investigation and improves understanding of details of substances. Since the quality of volume data which is acquired by CT and MRI devices is impacted by noisy, partial effect and bias seriously,...
Using the framework of quotient image model, this paper presented a median filtering-based method (MFQI) for the illumination normalization of facial images. The proposed method first uses adaptive median filtering to derive an estimation of the received light, and then uses the quotient image model for local illumination normalization. Compared with the other quotient image methods, MFQI does not...
Sublingual vein is one important diagnostic measurement in Tongue Diagnosis. Segmentation method of sublingual veins from the near infrared sublingual images is proposed in this paper. According to the characteristic of the captured near infrared sublingual images, the radial projection method based on watershed algorithm is firstly applied to acquire the entire contour of the sublingual region, and...
