An Analysis on Mammograms using KDA in Multi Transform Domain

Developing a robust Computer Aided Diagnosis (CADx) system for mammograms analysis has been the challenging task for years. The slight difference in X-ray attenuation between normal and abnormal glandular tissues makes the mammogram diagnosis complicated. The proposed CAD system discriminates the abnormal severity of mammograms into normal-benign (non-cancerous, non-spreadable), normalmalign (c...

Contrast Enhancement Using Wavelet Transform and Adaptive Denoising in Mammograms

Breast cancer is a dangerous disease for women worldwide. X-ray mammograms are typically used by radiologists for diagnosis of early-stage breast cancer to reduce the risk of mortality. In many cases they are not easy to be analyzed because mammograms are low contrast and very noisy. This paper proposes improved contrast enhancement and adaptive denoising in mammograms. First, mammograms are de...

Query Architecture Expansion in Web Using Fuzzy Multi Domain Ontology

Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...

Detection of Microcalcification Clusters in Mammograms Using Curvelet Transform

In this paper we present a new approach for computer aided detection of microcalcifications (MC) clusters in mammograms. The proposed method is done in two stages; the first stage is a preprocessing with histogram, in the second stage the ability of these filtered images in detecting microcalcification is done using the Curvelet Transform. The proposed method is applied to a database of 10 dens...

Channel Estimation and CFO Compensation in OFDM System Using Adaptive Filters in Wavelet Transform Domain

Abstarct In this paper, combination of channel, receiver frequency-dependent IQ imbalance and carrier frequency offset estimation under short cyclic prefix (CP) length are considered in OFDM system. An adaptive algorithm based on the set-membership filtering (SMF) algorithm is used to compensate for these impairments. In short CP length, per-tone equalization (PTEQ) structure is used to avoid i...
