Skeletonisation is a key process in character recognition in natural images. Under the assumption that a character is made of a stroke of uniform colour, with small variation in thickness, the process of recognising characters can be decomposed in the three steps. First the image is segmented, then each segment is transformed into a set of connected strokes (skeletonisation), which are then abs...

background: personal protection equipments (ppes) should be easily accessible to decrease contact with infecting factors and also should be used purposefully to effectively keep the health care personnel in a safe distance from the patient blood and body fluid which can easily infect the operating rooms personnel. this study aimed to find the operating rooms' personnel compliance with standards...

abstract this study aims to examine the use of religion heritage and application of the prophet job’s character mask. one of the important masks that have been used by contemporary poets is the prophet’s masks, especially the job of which the story exists in the quran. this character is a symbol of patience. darvish and sayyab are the most important poets who used the mask of this character.  e...

Label-equivalence-based connected-component labeling algorithms complete labeling in two or more raster scans. In the first scan, each foreground pixel is assigned a provisional label, and label equivalences between provisional labels are recorded. For doing this task, all conventional algorithms use the same mask that consists of four processed neighbor pixels to process every foreground pixel...

Based on the theory developed in DM3], a C++ program is described which computes function values and derivatives of reenable functions and integrals of products of reenable functions (called reenable integrals) for up to four factors in the integral in one and two dimensions. In the three-dimensional case, integrals with at most three factors can be computed. The routines calculate the desired ...

In the work, we rebuild the masks of well-known interpolatory symmetric subdivision schemes-binary 2n-point interpolatory schemes, the ternary 4-point interpolatory scheme using only the symmetry and the necessary condition for smoothness and the butterfly scheme, and the modified butterfly scheme using the factorization property. 2006 Elsevier Inc.

We are often required to retouch images in order to improve their visual appearance, by removing the visual discontinuities like breaks and damaged regions. Such retouching of images may be achieved by inpainting. Current techniques for image inpainting require the user to manually select the target regions to be inpainted. Very few techniques for automatically detecting the target regions for ...

This study reports a new integrated device for measuring oral and nasal airflow with lossless speech recording with preliminary results on Chinese plosives. An acoustically transparent fiber-made mask acts both as a material for airflow resistance and a support for partitioning oral and nasal chambers. Two pressure sensors placed directly on the mask measure air pressure signals that correspond...
