Cross-Lingual Attention-based Mechanism for Speech Emotion Recognition
Speech emotion recognition is one of the most emerging areas for emotion detection that may fall within the scope of affective computing. In this particular case, emotional speech files of spoken words delivered during verbal communication are of interest. The emotions of speech are investigated through sound and emotion in speech and are modeled through machine learning. Through machine learning, we performed a series of experiments on datasets like RAVDESS, TESS, SAVEE, and EMO-DB, which lean toward the objective that a Recurrent Neural Network (RNN) and (CLAF-SER): The Cross-Lingual Attention-Based Adversarial Framework for SER would be able to detect and classify such emotions as sadness, anger, happiness, neutrality, and fear. Features such as MFCC, LPCC, pitch, energy, and chroma were extracted before implementing the RNN. Through this model, TESS achieved the highest accuracy among the other datasets. However, CLAF-SER gives the best performance when all datasets are combined.

Experiencing the ongoing difficulties in the "security" field and upgrading the current standards by planning a cutting-edge innovation. Understood assurance of your cash in the bank being protected has consistently been the reality of concern. At the point when people were on the planet, they need cash for different things. As a long time, elapsed and with enormous advancement, individuals began bringing in cash, property, gems, and a lot of more valuable things. With enormous improvement, individuals wanted to get their income. It is not sufficient to have these embellishments, however, security of this is vital, for this reason, we keep them in bank storage. In any case, we regularly hear or read in a paper that some phony individual approaches the storage of someone else and has taken the cash. To conquer this sort of cheats, validation of the individual who needs to utilize the storage is vital.

A Novel Zernike Moment-Based Real-Time Head Pose and Gaze Estimation Framework for Accuracy-Sensitive Applications
A real-time head pose and gaze estimation (HPGE) algorithm has excellent potential for technological advancements either in human–machine or human–robot interactions. For example, in high-accuracy advent applications such as Driver’s Assistance System (DAS), HPGE plays a crucial role in omitting accidents and road hazards. In this paper, the authors propose a new hybrid framework for improved estimation by combining both the appearance and geometric-based conventional methods to extract local and global features. Therefore, the Zernike moments algorithm has been prominent in extracting rotation, scale, and illumination invariant features. Later, conventional discriminant algorithms were used to classify the head poses and gaze direction. Furthermore, the experiments were performed on standard datasets and real-time images to analyze the accuracy of the proposed algorithm. As a result, the proposed framework has immediately estimated the range of direction changes under different illumination conditions. We obtained an accuracy of ~85%; the average response time was 21.52 and 7.483 ms for estimating head poses and gaze, respectively, independent of illumination, background, and occlusion. The proposed method is promising for future developments of a robust system that is invariant even to blurring conditions and thus reaching much more significant performance enhancement.

A Multiple Criteria-Based Cost Function Using Wavelet and Edge Transformation for Medical Image Steganography
With the ever-increasing need for concealing messages within cover media like image, video, and audio, numerous attempts have been developed for steganography. Most of the steganographic techniques perform their embedding operation on the cover image without selecting a better location. The right selection of location for embedding the information can lead to high imperceptibility and robustness. Accordingly, in this paper, we develop a new cost function for estimating the cost of every pixel to identify the good location to embed the message data. The proposed cost estimation procedure utilizes multiple parameters like wavelet coefficient, edge transformation, and pixel intensity. The proposed cost matrix is then utilized to embed the message data into the cover media using an embedding integer. The proposed steganographic technique is experimented with two magnetic resonance brain images, and the results are analyzed with the peak-to-peak signal-to-noise ratio (PSNR) and mean square error. The robustness analysis ensured that the proposed steganographic technique outperforms the existing methods by reaching the maximum PSNR of 72.74 dB.
