OXSeg: Multidimensional attention UNet-based lip segmentation using semi-supervised lip contours [PDF]

open access: yesarXiv
Lip segmentation plays a crucial role in various domains, such as lip synchronization, lipreading, and diagnostics. However, the effectiveness of supervised lip segmentation is constrained by the availability of lip contour in the training phase. A further challenge with lip segmentation is its reliance on image quality , lighting, and skin tone ...

Visual Words for Automatic Lip-Reading [PDF]

open access: yesPhD thesis, the University of Buckingham, 2009, 2014
Lip reading is used to understand or interpret speech without hearing it, a technique especially mastered by people with hearing difficulties. The ability to lip read enables a person with a hearing impairment to communicate with others and to engage in social activities, which otherwise would be difficult.

Use of Pfeifer incision for treatment of unilateral incomplete cleft of lip

open access: yesSRM Journal of Research in Dental Sciences, 2017
Cleft lip (CL) is commonly classified as complete or incomplete. In incomplete CL, there is a minimal distortion of orofacial region. Most of the times, it is treated with incisions which are used for complete CL.

Theoretical evaluation of engine auxiliary inlet design for supersonic V/STOL aircraft [PDF]

open access: yes
A higher order panel method is used to evaluate the potential flow of a 2-D supersonic V/STOL inlet. A nonsymmetric analytical inlet model is developed to closely match a wind tunnel model tested at NASA-Lewis.
