TRIAC: A code for track measurements using image analysis tools
A computer program named TRIAC written in MATLAB has been developed for track recognition and track parameters measurements from images of the Solid State Nuclear Track Detectors CR39. The program using image analysis tools counts the number of tracks for dosimetry proposes and classifies the tracks according to their radii for the spectrometry of alpha-particles. Comparison of manual scanning ...
متن کاملLogistic discriminant analysis of breast cancer using ultrasound measurements
Background: Logistic discriminant method was applied to differentiate malignant from benign in a group of patients with proved breast lesions on the basis of ultrasonic parameters. Materials and Methods: Our database include 273 patients' ultrasonographic pictures consisting of 14 quantitative variables. The measured variables were ultrasound propagation velocity, acoustic impedence and attenua...
متن کاملDigital Image Analysis to Determine Pore Opening Size Distribution of Nonwoven Geotextiles
The filtration performance of a geotextile is controlled by its pore opening size distribution ~PSD!. Current methods for determining PSD are mostly indirect and contain inherent disadvantages. Recent technological advancements in image analysis offer great potential for a more accurate and direct way of determining the PSD of nonwoven geotextiles. A new and accurate method of image analysis fo...
متن کاملAnalysis of DRIE Uniformity
A quantitative model capturing pattern density effects in Deep Reactive Ion Etch (DRIE), which are important in MEMS, is presented. Our previous work has explored the causes of wafer-level variation and demonstrated die-to-die interactions resulting from pattern density and reactant species consumption. Several reports have focused on experimental evidence and modeling of feature level (aspect ...
متن کاملEfficient single image non-uniformity correction algorithm
This paper introduces a new way to correct the non-uniformity (NU) in uncooled infrared-type images. The main defect of these uncooled images is the lack of a column (resp. line) time-dependent cross-calibration, resulting in a strong column (resp. line) and time dependent noise. This problem can be considered as a 1D flicker of the columns inside each frame. Thus, classic movie deflickering al...
