This paper presents an integrated system for face detection and tracking in video sequences. The system consists of two modules, namely face detection and face tracking. The automatic face detection is based on a non-holistic object detection approach that utilizes the appearance and the topology of facial components to robustly detect faces in images. Both statistical and structural pattern re...

in developing countries, the domination of peripheral and dependent capitalism relations and the lack of appropriate structures and channels of attracting, this system have caused some kind of spatial-anatomic unbalances that has resulted in the appearance of single cities with national and regional prevalence. this situation is the main reason for small, medium and intermediate cities to lose ...

This acoustic study explored dialect effects on realization of nuclear pitch accents in three regional varieties of American English spoken in central Ohio, southeastern Wisconsin and western North Carolina. Fundamental frequency (f0) change from vowel onset to offset in the most prominent syllable in a sentence was examined along four parameters: maximum f0 change, relative location of f0 maxi...

OBJECTIVES/HYPOTHESIS To determine the pattern of spread of WDTC to regional lymph nodes, in patients who presented with clinically positive nodes. STUDY DESIGN Retrospective chart review. MATERIALS AND METHODS Between October 2001 and December 2006, a total of 27 consecutive patients (12 males, 15 females) with clinical evidence of cervical metastasis of well-differentiated thyroid carcino...

The objective of this study was to investigate regional gradient of a synthetic cardiovascular burden (CVRB) in Croatia. Analysis was based on a multistage stratified sample representative of general adult population in six regions of Croatia (Croatian Adult Health Survey). Synthetic CVRB was defined by incidents (heart attack, stroke), blood pressure, overweight/obesity (BMI, waist circumferen...

We describe a method for pattern extraction by adaptive propagation of a regional threshold to the rest of the image. In most images there is an easily thresholded region. We propagate the regional threshold to the entire image using a linear approximation of the image intensity gradients. This method is useful in the fields where the extraction of precise geometry of the binarized patterns is ...

Existing data mining techniques mostly focus on finding global patterns and lack the ability to systematically discover regional patterns. Most relationships in spatial datasets are regional; therefore there is a great need to extract regional knowledge from spatial datasets. This paper proposes a novel framework to discover interesting regions characterized by “strong regional correlation rela...
