Image Encryption based on the RGB PIXEL Transposition and Shuffling Abstract — Privacy is one of the key issues information Security addresses. Through encryption one can prevent a third party from understanding raw data during signal transmission. The encryption methods for enhancing the security of digital contents has gained high significance in the current era of breach of security and misuse of the confidential information intercepted and misused by the unauthorized parties. This paper sets out to contribute to the general body of knowledge in the area of cryptography application and by developing a cipher algorithm for image encryption of m*n size by shuffling the RGB pixel values. The algorithm ultimately makes it possible for encryption and decryption of the images based on the RGB pixel. The algorithm was implemented using MATLAB. Index Terms — Cryptography, Encryption, algorithm, cipher image

是跟踪一个运动的篮球。采用的是Kalman滤波器与基于均值平移的目标跟踪算法相融合的扩展算法，为了跟踪快速运动的目标，首先对目标运动模型进行建模，并运用Kalman滤波器对目标在下一帧中的状态进行预测，并将此预测值作为均值平移算法搜索目标的起始点。(Is tracking a movement of the basketball. Kalman filter is used in the target mean shift based tracking algorithm extension of the integration algorithm, in order to track the fast-moving target, the first model of the target motion model and use Kalman filter to the target in the next frame of the state prediction, and the predictive value of the mean shift algorithm as the starting point of the search target.)
