The multimedia data can be tampered with, and the attackers can then claim its ownership. Image watermarking is a technique that is used for copyright protection and authentication of multimedia. Abstract:Background: Nowadays, information security is one of the most significant issues of social networks. Objective: We aim to create a new and more robust image watermarking technique to prevent illegal copying, editing and distribution of media.

Method: The watermarking technique proposed in this paper pdf roche non-blind and employs Lifting Wavelet Transform on the cover image to decompose the image into four coefficient matrices.

Then Discrete Cosine Transform is applied which separates a selected coefficient matrix into different frequencies and later Singular Value Decomposition is applied. Singular Value Decomposition is also applied to the watermarking image and it is added to the singular matrix of the cover image, which is then normalized, followed by the inverse Singular Value Decomposition, inverse Discrete Cosine Transform and inverse Lifting Wavelet Transform respectively to obtain an embedded image.

Normalization is proposed as an alternative to the traditional scaling factor. Results: Our technique is tested against attacks like rotation, resizing, cropping, noise addition and filtering. The performance comparison is evaluated based on Peak Signal to Noise Ratio, Structural Similarity Index Measure, and Normalized Visken (Pindolol)- FDA. Conclusion: The experimental results prove that the proposed method performs better Selpercatinib Capsules (Retevmo)- FDA other state-of-the-art techniques and can be used to protect multimedia ownership.

These systems are deployed in different environments such as clean or noisy and are used by all ages or types of people. These also present some of Selpercatinib Capsules (Retevmo)- FDA major difficulties faced in the development of an ASR system. Thus, an ASR system needs to be efficient, while also being accurate and robust. Our main goal is to minimize the error rate during training as well as testing phases, while implementing an ASR system. The performance of ASR depends upon different combinations of feature extraction techniques and back-end techniques.

In this paper, using a continuous speech recognition system, the performance comparison of different combinations of feature extraction techniques and various types Selpercatinib Capsules (Retevmo)- FDA back-end techniques has been presented.

Mel frequency Cepstral Coefficient (MFCC), Perceptual Linear Prediction (PLP), and Gammatone Frequency Cepstral coefficients (GFCC) are used as feature extraction techniques at the front-end of the proposed system.

Kaldi toolkit has been used for the implementation of the proposed work. The system is trained on the Texas Instruments-Massachusetts Institute of Technology (TIMIT) speech corpus for English language.

Results: The experimental results show that MFCC outperforms GFCC and PLP in noiseless conditions, while PLP tends to outperform MFCC and GFCC in noisy conditions. Conclusion: Automatic Speech recognition has numerous applications in our lives like Home mood not in the mood, Personal assistant, Robotics, etc.

It is highly desirable to build an ASR system with good performance. The performance of Automatic Speech Recognition is affected by various factors which include vocabulary size, whether the system is speaker dependent or independent, whether speech is isolated, discontinuous or continuous, and adverse conditions like noise. Discussion: The presented work in this paper discusses the performance comparison of continuous ASR systems developed using different combinations of front-end feature extraction (MFCC, PLP, and GFCC) and back-end acoustic modeling (mono-phone, tri-phone, SGMM, DNN and hybrid DNN-SGMM) techniques.

Each type of front-end technique is tested in combination with each type of back-end technique. Finally, it compares the results of the combinations thus formed, to find out the best performing combination in noisy and clean conditions. Also, with technological advancement, large amounts of data are produced by people.

The data is in the forms of text, images and videos. Hence, there is a need for significant efforts and means of devising methodologies for analyzing and summarizing them to manage with the space constraints. The keyframe Selpercatinib Capsules (Retevmo)- FDA is done based on fish oil omega 3 learning-based object detection techniques.

Various object detection algorithms have been Influenza Virus Vaccine (Flulaval)- Multum for generating and selecting the best possible frames as keyframes. A set of frames is extracted out of the original video sequence and based on the technique used, one or more Selpercatinib Capsules (Retevmo)- FDA of Selpercatinib Capsules (Retevmo)- FDA set are decided as a keyframe, which then becomes the part of the summarized video.

The following paper discusses the selection of various keyframe extraction techniques msac detail. Methods: The research paper is focused on the summary generation for office surveillance videos.

The major focus of the summary generation is based on various keyframe extraction techniques. For the same, various training models like Mobilenet, SSD, and YOLO Selpercatinib Capsules (Retevmo)- FDA used.

A comparative analysis of the efficiency for the same showed that YOLO gives better performance as compared to the other models. Keyframe selection techniques like sufficient content change, maximum frame coverage, minimum correlation, curve simplification, and clustering based on human presence in the frame have been implemented.

Results: Variable and fixed-length video summaries were generated and analyzed for each Selpercatinib Capsules (Retevmo)- FDA selection technique for office surveillance videos. The analysis shows that the output video obtained after using the Clustering and the Curve Simplification approaches is compressed to half the size of the actual video but requires considerably less storage space.

The technique depending on the change of frame content between consecutive frames for keyframe selection produces the best output for office surveillance videos. Conclusion: In this paper, we discussed the process of generating a synopsis of a video to highlight the important portions and discard the trivial and redundant parts. Firstly, we have described various object detection Selpercatinib Capsules (Retevmo)- FDA like YOLO and SSD, used in conjunction with neural networks like MobileNet, to obtain Selpercatinib Capsules (Retevmo)- FDA probabilistic score of an object that is present in the video.

These algorithms generate the probability of a person being a part of the image for every frame in the input video. The results of object detection are passed to keyframe extraction algorithms to obtain the summarized video. Our comparative analysis for keyframe selection techniques for office videos will help in determining which keyframe selection technique is preferable. Feature model is used to capture and organize features used Selpercatinib Capsules (Retevmo)- FDA different multiple organizations.
