A Framework for Medical Images Classification Using Soft Set

AbstractMedical images classification is a significant research area that receives growing attention from both the research community and medicine industry. It addresses the problem of diagnosis, analysis and teaching purposes in medicine. For these several medical imaging modalities and applications based on data mining techniques have been proposed and developed. Thus, the primary objective of medical images classification is not only to achieve good accuracy but to understand which parts of anatomy are affected by the disease to help clinicians in early diagnosis of the pathology and in learning the progression of a disease. This furnishes motivation from the advancement in data mining techniques and particularly in soft set, to propose a classification algorithm based on the notions of soft set theory. As a result, a new framework for medical imaging classification consisting of six phases namely: data acquisition, data pre-processing, data partition, soft set classifier, data analysis and performance evolution is presented. It is expected that soft set classifier will provide better results in terms of sensitivity, specificity, running time and overall classifier accuracy

Job Embeddedness: Factors and Barriers of Persons with Disabilities

Addressing the employment problems facing persons with disabilities (PWDs) is complicated as it depends on the presence of certain core values of others such as non-discrimination, in order to recognise their capabilities. PWDs can engage in many economic activities in Pakistan, however, in general, the employment rate for PWDs is relatively low. Qualitative research was used to ascertain insight into a central phenomenon. Data was collected through interviews and observation from five different workplaces through purposive sampling, and a thematic analysis technique was used to analyse the data. The participants were 50 years or less and were mainly men who had worked with people with disabilities for 2-5 years The study revealed that the major issue of employers was their perception that PWDs were less productive than those employees without a disability.  The study reported that the responsibility to create a positive image and to think inclusively about PWD’s working capabilities was the responsibility of the persons with disabilities

Medical data classification using similarity measure of fuzzy soft set based distance measure

Medical data classification plays a crucial role in many medical imaging applications by automating or facilitating the delineation of medical images. A considerable amount of literature has been published on medical images classification based on data mining techniques to develop intelligent medical decision support systems to help the physicians. This paper assesses the performance of a new classification algorithm using similarity measure fuzzy soft set based distance based for numerical medical datasets. The proposed modelling comprises of five phases explicitly: data acquisition, data pre-processing, data partitioning, classification using FussCyier and performance evaluation. The proposed classifier FussCyier is evaluated on five performance matrices’: accuracy, precision, recall, F-Micro and computational time. Experimental results indicate that the proposed classifier performed comparatively better with existing fuzzy soft classifiers

Exponential smoothing techniques on daily temperature level data

The changes of temperature level occur throughout the year.This event whether hot temperature or cold temperature can affect human life and nature. Such event is also known as extreme event due to the nature of the data produced.Usually the time series of extreme dataset is rarely linear.The existence of nonlinear pattern and high fluctuation in variation greatly affect the quality of forecasting performances.Three exponential smoothing techniques have been tested to study their ability in handling of temperature level data from three cities in Texas.Single Exponential Smoothing Technique (SEST), Double Exponential Smoothing Technique (DEST) and Holt’s method were explored in preparing the temperature data.From the experiments, it was found that DEST is the most suitable technique to deal with the data compared to SEST and Holt's method

FussCyier: Mamogram images classification based on similarity measure fuzzy soft set

Automatic digital mammograms reading become highly enviable, as the number of mammograms to be examined by physician increases enormously.It is premised that the computer aided diagnosis system is mandatory to assist physicians/radiologists to achieve high efficiency and productivity.To handle uncertainties of medical images, fuzzy soft set theory has been merely scrutinized, even though the choice of convenient parameterization makes fuzzy soft set suitable and feasible for decision making applications. Therefore, this study investigates the practicability of fuzzy soft set for classification of digital mammogram images to increase the classification accuracy while lower the classifier complexity.The proposed method FussCyier involves three phases namely: pre-processing, training and testing.Results of the research indicated that proposed method gives high classification performance with wavelet de-noise filter Sym8 with the accuracy 75.64%, recall 84.67% and CPU time 0.0026 seconds

Thresholding and quantization algorithms for image compression techniques: a review

With increasing demand on digital images, there is a need to compress the image to entertain the limited bandwidth and storage capacity. Recently, there is a growing interest among researchers focusing on compression of various types of images and data. Amongst various compression algorithms, transform-based compression is one of the promising algorithms. Despite the technological advances in transmission and storage, the demands placed on the bandwidth of communication and storage capacities by far outstrips its availability. This paper presents a review of image compression principle, compression techniques and various thresholding algorithms (pre-processing algorithms) and quantization algorithm (post-processing algorithms). This paper intends to give an overview to the relevant parties to choose the suitable image compression algorithms to suit with the need

Consolidating Literature for Images Compression and Its Techniques

With the proliferation of readily available image content, image compression has become a topic of considerable importance. As, rapidly increase of digital imaging demand, storage capability aspect should be considered. Therefore, image compression refers to reducing the size of image for minimizing storage without harming the image quality. Thus, an appropriate technique is needed for image compression for saving capacity as well as not losing valuable information. This paper consolidates literature whose characteristics have focused on image compression, thresholding algorithms, quantization algorithms. Later, related research on these areas are presented

The Effect on Compressed Image Quality using Standard Deviation-Based Thresholding Algorithm

In recent decades, digital images have become increasingly important. With many modern applications use image graphics extensively, it tends to burden both the storage and transmission process. Despite the technological advances in storage and transmission, the demands placed on storage and bandwidth capacities still exceeded its availability. Compression is one of the solutions to this problem but elimination some of the data degrades the image quality. Therefore, the Standard Deviation-Based Thresholding Algorithm is proposed to estimate an accurate threshold value for a better-compressed image quality. The threshold value is obtained by examining the wavelet coefficients dispersion on each wavelet subband using Standard Deviation concept. The resulting compressed image shows a better image quality with PSNR value above 40dB

Application of Wavelet de-noising Filters in Mammogram Images Classification Using Fuzzy Soft Set

Recent advances in the field of image processing have revealed that the level of noise in mammogram images highly affect the images quality and classification performance of the classifiers. Whilst, numerous data mining techniques have been developed to achieve high efficiency and effectiveness for computer aided diagnosis systems. However, fuzzy soft set theory has been merely experimented for medical images. Thus, this study proposed a classifier based on fuzzy soft set with embedding wavelet de-noising filters. Therefore, the proposed methodology involved five steps namely: MIAS dataset, wavelet de-noising filters hard and soft threshold, region of interest identification, feature extraction and classification. Therefore, the feasibility of fuzzy soft set for classification of mammograms images has been scrutinized. Experimental results show that proposed classifier FussCyier provides the classification performance with Daub3 (Level 1) with accuracy 75.64% (hard threshold), precision 46.11%, recall 84.67%, F-Micro 60%. Thus, the results provide an alternative technique to categorize mammogram images. Keywords: Mammogram images; Feature extraction; Wavelet filters; Fuzzy soft set
