In order to solve the camera calibration in intelligent space of mobile robot, a new calibration method based on neural network with tunable activation function (TAF) is presented. In the TAF model, the inner product mode is adopted in the calculation of output signal in synapse model and the S function is adopted in base function. Taking the coordinate in image coordinate system as the network input, and the coordinate in world coordinate system as the network output, the weight matrix, threshold matrix and activation function parameter are achieved firstly through the network training based on sample data, then the calibration test are carried out using the TAF network which is trained. The experiment results show that, compared with the test results of BP network, the proposed calibration method is characterized by high detection precision and quick detection speed, which verifies the validity of TAF network in camera calibration.

In this paper, the modified prominent point processing (MPPP) approach for the phase compensation in inverse synthetic aperture radar (ISAR) imaging is proposed. It applies the minimum entropy method (MEM) to find the prominent point cell used for the phase calibration. After minusing the measured phase value of prominent point range cell from all the range bins belonged to the same echo, a well-focused ISAR image can be obtained by combining all the range bins. Compared to the PPP algorithm, the MPPP method can find the better prominent point unit utilized for the phase correction, which will lead to a more focused ISAR image after the phase compensation. The simulation result proves that the proposed approach can enhance the clarity and focusing of the ISAR image.

In this paper, we present a novel system which allows its users to see a stereoscopic virtual object. Unlike most existing stereoscopic systems that display the same imagery when watched from different directions, the user's head is tracked in real-time so that the real-time images can be rendered according to the viewing position, which enables the dynamic images to be displayed on the screen and the users can see different parts of a virtual object when wearing a pair of polarized glasses. This creates a more vivid illusion that a real object is set at the physical scene. The key technologies of the proposed system such as depth-image-based head tracking, geometric calibration and view-dependent real-time stereoscopic image rendering are studied and the experimental results proves the performance of the proposed system.

HLA has become the mainstream of distributed simulation technology, but serial execution of simulation objects in the existing HLA run-time infrastructure results in huge computation and communication bottlenecks. It has been becoming a focus of attention to accomplish the parallel scheduling of HLA simulation application. This paper proposed a method for parallel scheduling of HLA-based simulation objects. We introduced the base classes named SimObject and Interaction to map object attributes and interaction parameters from FOM files to object instances and interaction instances, and constructed additional three new service components: simulation manager, object manager, interaction manager. This way, simulation objects in a federate or across different federates can be scheduled in parallel, improving the running efficiency of simulation system.

Detecting the boundary of television screen is the basis of content identification for human-computer interaction. Uncertainty exists in TV video image which is captured by mobile phone because of the resolution, color, brightness, background. The reduction of image quality leads to inaccurate identification. We propose a method based on the feature of TV's shape to segment the TV screen indirectly. Our approach aims at extracting the typical feature between the background and objective image. The experimental results demonstrate the effectiveness of the proposed approach for TV screen shape.
