Abstract. We present a novel method for detecting rotated lungs in chest radiographs for quality control and augmenting automated abnormality detection. The method computes a principal rib-orientation measure using a generalized line histogram technique for quality control, and therefore augmenting automated abnormality detection. To compute the line histogram, we use line seed filters as kerne...

Gabor features encoded by local binary pattern, could achieve state-of-the-art FR results in large-scale face databases.However, the time and space complexityof Gabor transformation are too high for many practicalFR applications. We propose a new and efficient local feature extraction scheme, namely MONOGENIC BINARY CODING (MBC), for face representation and recognition. The original signal is d...

Three techniques are presented which use assumptions about the real world to determine the orientation of objects from a single visual image. The orientation information from each of these techniques is combined to provide a more accurate estimate of object orientation. This algorithm is applied to the task of estimating the orientation of a single transistor against a uniform, but contrasting,...

many researchers adopt local binary pattern for pattern analysis. however, the long histogram created by local binary pattern is not suitable for large-scale facial database. this paper presents a simple facial pattern descriptor for facial expression recognition. local pattern is computed based on local gradient flow from one side to another side through the center pixel in a 3x3 pixels region...

In this paper we propose a novel face recognition algorithm based on orientation histogram of Hough Transform Peaks. The novelty of the approach lies in utilizing Hough Transform peaks for determining the orientation angles and computing the histogram from it. For extraction of feature vectors first the images are divided into non overlapping blocks of equal size. Then for each of the blocks th...

Beam orientation optimization (BOO) is a key component in the process of intensity modulated radiation therapy treatment planning. It determines to what degree one can achieve a good treatment plan in the subsequent plan optimization process. In this paper, we have developed a BOO algorithm via adaptive l(2, 1)-minimization. Specifically, we introduce a sparsity objective function term into our...

aim: considering the fundamental role of parents' function and family dynamics including the importance role of family communication pattern on preventing early-onset substance use in children, the present study aimed to determine the correlation between family communication pattern and mothers' preventive behavioral intention regarding preventing early-onset substance use in children...

For the Visual Concept Detection of CLEF 2010 Challenge, using only visual information, we propose a novel multi-level spatial pyramidal (sp) features : the spELBP (Extended Local Binary Pattern). In this paper we first present these features and few others that are similar : the spELBOP (Extended Local Binary Orientation Pattern), and the spHOEE (Histogram of Oriented Edge Energy). Then we dis...
