Specific genetic profiles of Brazilian Biomphalaria species were previously standardized by molecular taxonomy through the analysis of restriction fragments, which were generated by digesting the internal transcribed spacer region of rDNA with the DdeI endonuclease. Biomphalaria amazonica displayed three distinct profiles. To investigate these distinct profiles, the same molecular technique, po...

A new method for face recognition using profile gray-level images based on the morphological signature transform (MST) is presented in this paper. Gray-level image of profile is thresholded to produce a binary, black and white image. The method is based on the successive morphological erosions of the input profile at different resolutions by primary and rotated structuring elements. The areas o...

A novel method for face recognition using profile images based on the representation of the original and morphological derived profile shapes is presented in this paper. The goal of our approach is to use information from profile outline that bounds the face and the hair. A grey-level profile image is thresholded to produce a binary image, representing the face region. After normalising the are...
