ABSTRACT

With the advancement of internet technology, the numbers of threats are also rising exponentially. To reduce the impact of these threats, researchers have proposed many solutions for intrusion detection. In the literature, various machine learning classifiers are trained on older datasets for intrusion detection which limits their detection accuracy. So, there is a need to train the machine learning classifiers on latest dataset. In this paper, UNSW-NB15, the latest dataset is used to train machine learning classifiers. On the basis of theoretical analysis, taxonomy is proposed in terms of lazy and eager learners. From this proposed taxonomy, K-Nearest Neighbors (KNN), Stochastic Gradient Descent (SGD), Decision Tree (DT), Random Forest (RF), Logistic Regression (LR) and Naïve Bayes (NB) classifiers are selected for training. The performance of these classifiers is tested in terms of Accuracy, MSE, Precision, Recall, F1-Score, TPR and FPR on UNSW-NB15 dataset and comparative analysis of these machine learning classifiers is carried out.

Jagan Raj Jayapandiyan¹, C. Kavitha² and K. Sakthivel³, ¹Periyar University, India, ²Thiruvalluvar Govt. Arts College, India, ³K. S. Rangasamy College of Technology, India

ABSTRACT

In this proposed research work, an attempt has been made to use multiple image files for steganography encoding along with the capability of secret text recovery in the event of any image corruption during the transit. This algorithm is effective on the security factor of secret image since the embedded checksum will validate for any unauthorized users or intruders attempt to corrupt the picture in any aspect. If any of the stego image underwent any steganalysis or MiM attack, then this proposed algorithm can effectively regenerate the content of one stego image using other intact stego images received in the receiving end.

Design of efficient dual character paradigm based P300 speller system and performing spectral analysis of EEG signals

Perla Abhinay Sai and Praneeth Sai, Electrical Engineering, National Institute Of Technology Raipur, India

ABSTRACT

Brain-computer interfaces (BCI) are systems that allow communication between the brain and computer. Their working basically consists of three sections: collecting the brain signal, interpreting the brain signal and in the end sending the commands to a connected machine in accordance to the brain signal received. Instead of depending on peripheral nerves and muscles, a BCI directly measures brain activity associated with the user’s intent and translates the recorded brain activity into corresponding control signals for BCI applications. An event-related potential, which is generated during the process of decision making is called as P300 wave as it has a positive peak at 300ms after visual stimulation. This report aims to detect the P300 wave from acquired EEG signal accurately. The existing R/C paradigms suffer from various problems such as crowding effect due large size as well as error related potential generation due to counting by subjects. Therefore, we came up with an idea to use dual character R/C paradigm which address the above issues by reducing size and using voluntary eye closure instead of counting. This will in turn lead to a significant increase in character detection. Therefore, people with severe motor neuron disability, suffering from amyotrophic lateral sclerosis (ALS) or brain injuries will be able to communicate with the people around them with ease.

Biometric Fetal Contour Extraction using Hybrid Level Set

Rachana Jaiswal and Srikant Satarkar, Department of Computer Science & Engineering, Amravati University, Akola, MH

ABSTRACT

In medical imaging, accurate anatomical structure extraction is important for diagnosis and therapeutic interventional planning. So, for easier, quicker and accurate diagnosis of medical images, image processing technologies may be employed in analysis and feature extraction of medical images. In this paper, some modifications to level set algorithm are made and modified algorithm is used for extracting contour of objects in an image. The proposed approach is applied on fetal ultrasound images. In traditional approach, fetal parameters are extracted manually from ultrasound images. Due to lack of consistency and accuracy of manual measurements, an automatic technique is highly desirable to obtain fetal biometric measurements. This proposed approach is based on global & local region information for fetal contour extraction from ultrasonic images. The primary goal of this research is to provide a new methodology to aid the analysis and feature extraction from fetal images.

Segmentation of Dermatoscopic images using wavelet Transform

Kanchan A. Nandedkar, MGM’s college of Computer Science & Information Technology, Nanded-431605 (Maharashtra)

ABSTRACT

Wavelet based segmentation provides a very effective technique for medical images. Automatic segmentation of skin lesions is the first step towards development of computer aided diagnosis of melanoma. This paper provides an improved automated skin lesion segmentation method for color dermoscopic images. A novel wavelet transform based technique called “Segmentation of Dermatoscopic images using wavelet transform” (SDIWT) is proposed. One of the important advantages of wavelet transform is that it provides a precise and unifying framework for the analysis and characterization of a signal at different levels. SDIWT uses a perceptually uniform color space for segmentation. To reduce computational complexity for clustering, prominent pixels are selected. One level decomposition of Daubechies wavelet function is used. LL1 sub band of decomposition is utilized for clustering. Fuzzy c- means (FCM) clustering technique is used to find out clusters and their labels. Fuzzy entropy is used to decide number of clusters. The image pixels are classified to respective clusters based on minimum Euclidean distance. A post processing noise filtering stage is applied to improve the segmentation output. Edges are determined to specify the lesion from Dermatoscopic images. One of the advantages of the proposed method is that it does not require to specify a priori information to segment a color region. The competence of the proposed method has been demonstrated by various experiments.

Image Processing Failure and Deep Learning Success in Lawn Measurement

J. Wilkins¹, M. V. Nguyen¹ and B. Rahmani^{1, 2}, ¹Fontbonne University, USA, ²Maryville University, USA

ABSTRACT

Lawn area measurement is an application of image processing and deep learning. Researchers used hierarchical networks, segmented images, and other methods to measure the lawn area. Methods’ effectiveness and accuracy varies. In this project, image processing and deep learning methods were used to find the best way to measure the lawn area. Three image processing methods using OpenCV compared to convolutional neural network, which is one of the most famous, and effective deep learning methods. We used Keras and TensorFlow to estimate the lawn area. Convolutional neural network or shortly CNN shows very high accuracy (94-97%). In image processing methods, thresholding with 80-87% accuracy and edge detection are the most effective methods to measure the lawn area while the method ofcontouring with 26-31% accuracy does not calculate the lawn area successfully. We may conclude that deep learning methods, especially CNN, could be the best detective method comparing to image processing learning techniques.

ABSTRACT

In today’s world, with the increasing demand of products and their growing productivity from producers, customers sometimes failed to decide whether they are interested in buying a particular product or not. So author, here proposed a framework which deals with the buying of only items of interest, for a consumer. In our feature-set, whenever any consumer tends to watch any video from YouTube, it results in breakdown into several frames (frames per second), and from there we use object detection technique to detect each and every object in a particular frame, and then to find whether our consumer is interested in that particular object or not, we use facial emotion detector to check whether our user is happy, surprised, neutral or any other emotion. After viewing those products which are present in a frame of a video. Merging only those items of interest which were tend to fall for consumer’s positive choices (emotions), we then used Amazon online marketing technique to recommend products selected by our framework.

ABSTRACT

The COVID-19 infection caused by Novel Corona Virus has been declared a pandemic and a public health emergency of international concern. Infections caused by Corona Virus have been previously recognized in people and is known to cause Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). Unlike the earlier infections, COVID-19 spreads alarmingly and the experience and volume of the scientific knowledge on the virus is small and lacks substantiation. To manage this crisis, Artificial intelligence (AI) promises to play a key role in understanding and addressing the COVID-19 crisis. It tends to be valuable to identify the infection, analyse it, treat it and also predict the stages of infection.Artificial intelligence algorithms can be applied to make diagnosis of COVID-19 and stepping up research and therapy. The paper explains a detailed flowchart of COVID-19 patient and discusses the use of AI at various stages. The preliminary contribution of the paper is in identifying the stages where the use of Artificial Intelligence and its allied fields can help in managing COVID-19 patient and paves a road for systematic research in future.
