Multi-focus imaging fusion is a technique that puts together a fully focused object from the partly focused regions of several objects from the same scene. For producing a high quality fused image, directional selectivity and invariance characteristics are important. The ringed artifacts, however, were inserted into a fused image because of a lack of invariance and misdirection. A multi-focus image fusion algorithm is proposed to resolve these issues, in conjunction with qshiftN dual-tree complex wavelet transform and modified principal component analysis. First, the source images are translated into the FP domain. It helps in the obtaining of the row frequency components and column frequency components. Then the row-frequency elements and column-frequency elements are combined with a dual tree-complex wavelet qshiftN to transform the origin frames. Dual tree complex wavelet transforms with qshiftN has demonstrated that it provides an effective transformation for multi-resolution imaging fusion with its directional and shift-invariant characteristics. To enlarge the effectiveness of the qshiftN dual-tree complex wavelet transform in frequency partition-based method, the modified principal component analysis (MPCA) algorithm is used. The proposed fusion approach has been tested on a numeral of multi-focus images and compared to various popular methods of imaging fusion. The experimental results indicate that in subjective performance and objective assessment, the proposed fusion approach could deliver better fusion results.Keywords

Multi-focus imaging fusion is a technique that puts together a fully focused object from the partly focused regions of several objects from the same scene. For producing a high quality fused image, negligible aliasing, and the ability to separate positive from negative frequencies characteristics are important. The ringed artifacts, however, were inserted into a fused image because of a lack of negligible aliasing and the ability to separate positive from negative frequencies properties. A multifocus image fusion algorithm is proposed to resolve these issues, in conjunction with multiresolution and modified principal component analysis. In this, two identical multi-focus images are considered, first they are subjected to the multi-resolution and then to the technique of modified principal component analysis. The multiresolution improves essential image features, which are best used in fusion of images, resulting in good image quality. Modified principal component analysis is applied to reduce the dimensionality of an image. The proposed fusion approach has been tested on a numeral of multifocus images and compared to various popular methods of imaging fusion. The experimental results indicate that in subjective performance and objective assessment, the proposed fusion approach could deliver better fusion results.Keywords

Understanding the action of human plays an important role in public gatherings and recognition of human action is a major problem which leads to analysis the human activities. In many years, people are interested for detecting the human activity. Human behavior analysis are used in many areas like video surveillance, banks to increase public security. To detect the human behavior from the videos, essential features are to be detected. The major challenge in human action recognition is to generate the required features significance changes occurred in human action. Nowadays skeleton data-based action detection becoming more popular. In order to counterpart such limitations, this paper brings a method using Skeleton Graph based deep learning convolutional neural network. The proposed method gives accuracy of 0.93.Keywords
