چکیده

3D face" S3D can be utilized to generate the 3D facial caricature Q3D as given in the eq. (1). This general idea of We proposed a method of 3D caricature generation 3D caricaturing is shown in Fig. 1. which is based on the automatic extraction of the facial parts for the 3D facial image. This method is likely to suffer sometimes fatal degradations in the feature extraction 81, = &D + b ( L S ~ D ) (1) from a variation of the head pose (roll, pitch and yaw). Therefore, we propose a method of facial image modification by rotation (roll) which is based on the irises position extracted by Hough transform of the circle from gray scale image. We improved the facial feature extraction rate and the quality of the caricature generated by the improved 3D face data.

Ultra-Fast Image Reconstruction of Tomosynthesis Mammography Using GPU

Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...
