This paper investigates the optimal estimation for continuous-time Markov jump linear (MJL) systems with multiplicative noises, where the multiplicative noise is with diagonal matrix form. Firstly, the complete mean square method is used to design the optimal MJL filter and the gain is obtained by solving the differential Ricatti equation. Secondly, the stable optimal filter is designed. Finally, a numerical example is given to show the efficiency of the method.

This paper introduces a novel image encryption algorithm by means of LSS-CML, compressive sensing (CS) and K-Principle Component Analysis (KPCA) method. Firstly, the original image is compressed using CS and the KPCA method, in which LSS-CML is utilized to construct the key-controlled pseudo-random measurement matrices. Then the compressed image is shuffled and diffused by the key streams produced from both the original image and LSS-CML. The initial conditions and parameters of LSS-CML are updated with the help of the original image and the hash function SUA-S12. Thus the key streams rely on both the plain-image and LSS-CML, which make the encryption approach resistance to the 2chosen-plaintext and known-plaintext attacks. Experimental results and performance analysis have verified the validity of the presented scheme.

In recent times, speech recognition technology has been applied in various industries, and it can control software to operation without touch which largely increase the convenience and friendliness of software application. In this paper, we design and implement a voice controlled music player using iFLYTEK open platform. The music player system which runs on android system integrates graphical touch control with intelligent voice control. The music player implements the operation of traditional graphical button interaction through voice interaction, which can replace some of the functions, such as playback control, song query, character input, etc. The system employs speech recognition API on iFLYTEK open platform. Our music player system can be woken up by speech recognition when the system is in suspend status. It has many other voice services, which facilitate the music player's interaction on mobile system. The experiment shows, it has high performance on software application and actual scenario use.

The temporal and spatial information of dipoles has been demonstrated to be very important in the decoding of MI-tasks. So, how to make full use of this information is very meaningful. In traditional dipole decoding methods, the spatial filters are applied to extract the spatial feature, which may not utilize the real position of the dipoles, resulting in a low recognition accuracy. In order to solve the problem, a dipole imaging method based on azimuthal equidistant projection (AEP) is proposed, named as AEPDI. Firstly, the dipoles coordinates and amplitudes within region of interest (ROI) and the region of time (TOI) are extracted; Then the 3D dipoles coordinates are projected onto XOY, XOZ and YOZ planes by AEP algorithm respectively. After a series of processing of the dipoles coordinates, the two-dimensional images of the dipoles are constructed. Finally, a multi-branch 3DCNN is designed to recognize the 3D feature data of the three planes. The abundant experiments show that dipole imaging method with the AEP algorithm can effectively improve the classification accuracy, and the multi-directional dipoles feature fusion achieves the highest classification accuracy.

Considering lateral-directional control of an unmanned aerial vehicle (UA V), a multi-input multi-output (MIMO) control law design method based on L1 adaptive control theory is proposed. To improve the performance of the multi-variable coupling control system, a L1 adaptive controller is introduced in the basic controller which is designed with augmented linear-quadratic regulator (LQR). Compared with the structure for single-input single-output (SISO), the L1 adaptive controller with MIMO structure shows better dynamic characteristics, tracking performance and robustness for multi-variable coupled systems. Simulation verifications both in the nominal state and maneuvering flight of the MIMO L1 adaptive control system are described.

Binocular vision is an important part of machine vision. This paper focuses on how to obtain the position information of the target in the three-dimensional space and designed a ranging method based on binocular stereo vision through the combination of software and hardware. Firstly, the binocular camera is calibrated to get the internal and external parameters, then the disparity map is obtained by stereo correction and matching. Finally, the 3D information is output by clicking the target on the disparity map, and through physical measurement distance to verify the reliability of the method.
