Abstract

In this paper, Qualitative metrics for object tracking algorithms is introduced. The two algorithms are subjectively analyzed, and four different types of datasets based on occlusion strength, contrast, illumination, and clutter are taken. Each dataset is of simple and hard type. Gaussian Mixture Model (GMM) and Weighted Running Window Background (WRWB) model based GMM are the two human tracking algorithms taken for subjective analysis. The algorithms are verified for both easy and hard type datasets. The performance metrics show that these parameters are best to analyze any object tracking algorithms subjectively. Precision and recall parameters are considered for subjective analysis.

Abstract

Brain tumor refers to the growth of abnormal tissues in human brain. Brain tumor can be cancerous or non-cancerous which may affect people of any age group. In this work, Gaussian Filter and Canny Edge Detection Technique for brain MRI segmentation are used. Gaussian filter is utilized to remove the noise and provide high quality images, whereas the Canny Edge Detector is used for Edge Detection process to detect all edges accurately and avoid the missing edges. The results obtained from this research work provide easy identification of tumor and to find out the exact location of tumor in human brain.

Abstract

Accuracy is one of the major concerns for any face recognition algorithm. A good preprocessing technique can increase the accuracy of a face recognition system. For this purpose, the authors present a preprocessing method for face recognition, which is helpful for training under-sampled images. For this purpose, different preprocessing techniques are taken and those methods are used during training and the resultant images are added back to the training set. Each individual preprocessing technique is helpful to tackle different conditions like lighting, disguise, etc. The training will be done using a deep convolutional neural network and a Voting Classifier. Further the results of the existing preprocessing methods are compared with the proposed model on LFW dataset. They have also used a technique to increase the accuracy of the system.

Abstract

Human face conveys more information about identification, expression, and emotions of a person. In today's world every individual in the society wants to be more secure from unauthorized authentication. In order to provide more security, “Facial Recognition” has come into the picture and lead a most challenging role of detecting the face with more accurate results without any false identities. To increase the efficiency of the face recognition, histogram based facial recognition is chosen, where a face region is fragmented into a number of regions and histogram values are extracted and they are linked together into a single vector. This vector is compared for the similarities between the facial images and provides a most efficient outcome.
