objective: since orthodontic and orthognathic treatment planningin each ethnic group must be done according to the soft tissue facial characteristicsregarded as beauty,they thus vary from country to country.the main purpose of this articlewas to determine the mean range of the middle third of soft tissue facial profile and anteroposterior lip positioningusing 3angular and 2 linear measurements ...

The authors proposed the texture unit-based texture spectrum approach in 1990, which has been used for texture analysis, including texture characterization, texture classification, texture edge detection, and textural filtering. One of the most important disadvantages related to this method is the large number of texture units (6,561) and its redundancy. This paper aims at simplifying the origi...

This paper uses theory, simulation, and laboratory experiment, to show that directional illumination, used during the image acquisition process, acts as a directional filter of three dimensional texture. It is shown that the directional characteristics of image texture are not intrinsic to the physical texture being imaged, as they are affected by the direction of the illumination. This result ...

Fruit textural characteristics can affect the storage, transportation, and processing of plum ( Prunus salicina Lindl) in commercial production. We analyzed 23 cultivars with marked differences fruit traits. Basic physicochemical indicators fruits were determined using puncture testing texture profile analysis. Furthermore, through combined application cluster analysis principal component analy...

The effect of irradiation through UV-C on the content phenolic compounds, antioxidant activity, color, and texture profile was evaluated in Bordô variety grapes. Grapes were subjected to stress by at time 0.5, 1.0, 4.0, 10 30 min that correspond doses 0.1, 0.3, 2.4, 7.2 kJ m-2, respectively. total anthocyanins content, color grapes after storage 22 ºC for 24 48 h. In general, samples irradiated...
