In order to address the plantar arch issue, the foot image was divided into three sections from the fingers to the heel, where each section contains 33.33% of the image.
Table 8 presents a comparative analysis of the execution time of the algorithms over the database of the human plantar arch images.
Figure 9 presents the results of the proposed method in different plantar arch images, where the rows, from (a) to (d), show the real images, the binary images, the edge images with the detected parabolas, and the output of the proposed method.
Therefore, the aims of the study were to: a) re-examine and describe the morphology of the plantar arterial arch, b) illustrate the morphometry of the plantar arterial arch, in particular, the length, diameter, form of the arch, and document its variations, c) determine the dominant contributors to the plantar arch, and d) compare the plantar arterial arch with regards to side symmetry and sex.
The relations of the plantar arch were noted, and the entire plantar arterial arch was clearly defined.
Predominant blood supply to the plantar arch was determined by measuring each commissure of the entire course of the plantar arch.
The collapse of the plantar arch in adulthood is closely linked to the professions which particularly demand this region (barbers, shop assistants, and waiters) or to some diseases which need immobilization on the long term (N.
SUI associated with dance is more closely related to the flexibility of the plantar arch in basal conditions ([r.sup.2] = 0.64, p < 0.05, t-stat = 3.57) and after training ([r.sup.2] = 0.76, p < 0.05, t-stat = 3.52), than that presenting in diverse situations ([r.sup.2] = 2.07, p < 0.05, t-stat = 3.1), for which other causal factors must be sought.
In the present study, anthropometric measurements of the internal plantar arch were taken with the dancer in relaxed two-footed stance (MAH-two-footed stance), with each foot supporting around half the body weight, the ankles in a neutral position, and the body in a normal upright position.
