This paper presents a novel texture-based algorithm for detecting certain kinds of meningiomas in images of neurosurgical resections. The algorithm employs Discriminant Wavelet Packet Transform (DWPT) and Learning Vector Quantization (LVQ). The adaptive DWPT of a test image is computed by maximizing the discrimination power of subbands during the basis selection process for the training images....

The present paper described the technique to evaluate digital resolution (DR), Visual Magnification (VM), onScreen Magnification (SM) and Useful magnification (US) in order to compare image quality and resolution for diagnostic purposes on computer assisted microscopes including Multi-Modal Miniature Microscopes-4M.The study was done on surgical pathology and cytological specimens comparing ana...

In this paper, we propose an integrated segmentation and recognition method using cascade neural network. In the proposed method, a new type of cascade neural network is developed to train the spatial dependences in connected handwritten numerals. This cascade neural network was originally extended from the multilayer feedforward neural network to improve the discrimination and generalization p...

Molecular markers serve to assign individual samples to specific groups. Such markers should be easily identified and have a high discrimination power, being highly conserved within groups while showing sufficient variability between the groups that are to be distinguished. The availability of a large number of complete genomic sequences now enables the informed selection of genes as molecular ...

The paper comparatively analyzes the speaker discrimination power of the vocal source and vocal tract related features and present a speaker verification system optimally utilizing the source and tract related speaker specific information. A pitchsynchronous wavelet transform is adopted to capture the speaker specific information from the vocal source signal, particularly the Linear Prediction ...

Eighteen autosomal microsatellite loci were examined using 275 Shiba Inus in Japan. Eighteen dogs representing eight trios were obtained from four breeders to calculate mutation rates, and 257 dogs kept by owners were collected through veterinary clinics throughout Japan to calculate population genetic parameters and estimate discrimination power. After two loci (INU005 and AHTk253) were exclud...

The level of quality in segmentation and classification tasks, operating on biomedical digital images, is strongly affected by the ability of the feature functions to map the input structures on “highly separated” data sets. This level of separation is strictly dependent by the “discriminatory power” of the chosen feature functions, meaning with this expression the property of the functions to ...

in the present study, the effect of 5-ht2a receptor blockers in ca1 region of rat hippocampus on spatial learning was assessed in a t-maze, a spatial discrimination task. rats were canulated bilaterally and injected daily vehicle (saline), 5-ht2a-selective antagonist, ketanserin (0.6, 1.2 or 2.4 µg/0.5 µl) and pirenperone (0.1, 0.3, 1.2 or 2.4 µg/0.5 µl) into the cannula 30 minutes before train...
