Steganography is the method by which we hide confidential information in digital media that includes images, audio, and video files. This is useful for sending confidential information without revealing its existence. This paper introduces a novel steganographic approach based on GrabCut segmentation, Advanced Encryption Standard (AES), Discrete Cosine Transform (DCT), and quantization. Our steganography approach addresses several limitations existing in traditional methods such as low embedding capacity, visual distortions in images, and vulnerability to attacks. The GrabCut algorithm is used to segment the image into foreground and background regions. DCT is used for efficient data hiding, whereas quantization helps to preserve the image quality. Our method also adds an extra layer of security by encrypting the secret message using AES before embedding. In comparison to the state-of-the-art approaches, our method gives a high Peak signal-to-Noise Ratio (PSNR) and low Mean Square Error (MSE) which indicates the efficiency of our approach. In addition to these, we also tested the robustness of our approach against different attacks.
In response to the problems existing in current methods for enhancing the quality of art works, this paper introduced a method for enhancing the quality of art works based on image processing technology. First, the ed...

Brain computer interfaces (BCI) are applications that allows user to interact with their environment through their brain waves patterns, in this context the detection of eye blinks seems a good way to perform basic interactions. Electroencephalography (EEG) are methods that allows recording of brain waves through invasives or non invasives methods, in the cases of BCI application the lesser the invasiveness the higher the applicability. As this work will focus on pattern recognition within brain waves we developped a machine learning based approach to detect and classify different actions. Additionnaly the differentiation for each eye allows better interactivity for BCI applications.
