The Gleason score was originally formulated to represent the heterogeneity of prostate cancer and helps stratify risk patients affected by this tumor. assigning represents an on H&E stain task performed pathologists upon histopathological examination needle biopsies or surgical specimens. In paper, we propose approach focused automatic classification. We exploit a set 18 radiomic features. ...

Hyperspectral sensors provide a large number of spectral bands. This massive and complex data structure of hyperspectral images presents a challenge to traditional data processing techniques. Therefore, reducing the dimensionality of hyperspectral images without losing important information is a very important issue for the remote sensing community. We propose to use overlap-based feature weigh...

Tumors are heterogeneous tissues consisting of multiple regions with distinct characteristics. Characterization of these intra-tumor regions can improve patient diagnosis and enable a better targeted treatment. Ideally, tissue characterization could be performed non-invasively, using medical imaging data, to derive per voxel a number of features, indicative of tissue properties. However, the hi...

the aims of this study were to detect helicobacter pylori (h. pylori) by culture, polymerase chain reaction (pcr) and histopathological methods, to determine the prevalence of active h. pylori infection in elazig province, east of turkey and to evaluate the relationship between h. pylori infection and sex. antrum and corpus samples of 184 turkish patients (85 male and 99 female, age range 17 to...

Breast cancer has a devastating effect on women. Different strategies of breast classification exist with minimal work done the prediction occurrence disease in potential carriers. In this study, predictive system been developed using bidirectional long short-term memory (BiLSTM) for feature extraction and learning while two-dimensional convolutional neural network (CNN) was used classification...

Breast cancer (BC) is currently the most common form of diagnosed worldwide with an incidence estimated at 2.26 million in 2020. Additionally, BC leading cause death. Many subtypes breast exist distinct biological features and which respond differently to various treatment modalities have different clinical outcomes. To ensure that sufferers receive lifesaving patients-tailored early, it crucia...

in this paper we address the issue of recognizing farsi handwritten words. two types of gradient features are extracted from a sliding vertical stripe which sweeps across a word image. these are directional and intensity gradient features. the feature vector extracted from each stripe is then coded using the self organizing map (som). in this method each word is modeled using the discrete hidde...
