Production of 3D sound for virtual auditory space needs interpolated head related impulse responses (HRIRs), due to limitation of real-time system for storing HRIR measurements. Fortunately, interpolation of HRIRs can reduce much cost and effort in measuring many HRIRs. This research analyses three interpolation techniques, namely bilinear rectangular, bilinear triangular, and tetrahedral by using PKUIOA HRTF Database. Bilinear triangular interpolation has been applied to estimate a target HRIR from 3 surrounding measured HRIRs that form a triangle. Accordingly, bilinear rectangular interpolation uses 4 surrounding rectangular measured HRIRs. These geometrical approaches compute weights from relative angular distances of a target HRIR from measured HRIRs. Tetrahedral interpolation, in other hand, is an interpolation technique in 3D using barycentric weights. An optimal framework in obtaining estimated HRIRs is proposed here by interpolating minimum phase HRIRs using tetrahedral interpolation.

Flexible sensing resistors are satisfied for general-purpose applications in recording interactive force during hand manipulation. However, FSR sensors are considerably sensitive to shear. In this paper, shear effect of a Tekscan FlexiForce A401 sensor was investigated with a reformed offset runout detection instrument. Sensor output increased caused by shear stress is significant with normal load decreased and shear stress increased. The calibration of FSR output is necessary because shear effect is not sensitive and removed instantly. Considering the linearity of shear stress and normal load, a regression fit demonstrated the relationship between FSR sensors output and combination of normal load and shear stress. With this fit model, the calibrated signal of force measured by FSR Sensor was more accurate for reviving interactive force during hand manipulation.

The quality of any control design can be judged by the resulting transient response. When an adaptive control law is used for linear time-invariant systems with unknown parameters, the resulting transients can be rather unsatisfactory. This problem persists when the adaptive controller receives information about the output of the plant through a wireless network. In this paper, we use the multiple model technique to improve the transient performance in this scenario. We demonstrate that the output of the plant tracks a specified reference trajectory despite packet loss and packet delay. We investigate and compare the multiple models, switching and tuning technique with the multiple model approach that uses second level adaptation. With fewer models, the latter technique uses all the information in these models when compared to the former method.

Single sperm detection and tracking has received increasing attentions since In Vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI) techniques were introduced. In this paper, we proposed an automated system to extract and track single sperm movement. Intersect Cortical Model (ICM) which is derived from Pulse Coupled Neural Network (PCNN) is employed to extract region coordinates and the centroid of the sperm head region. By using the extracted region and centroid as an automated initialization in the proposed method, mean shift based tracking algorithm is then used to track the sperm for the entire video. As a comparison, the proposed method Intersect Cortical Model-Mean shift (ICMMS) has been evaluated with conventional mean shift based tracking method. From the results, the proposed ICMMS method remedies the drawback of mean shift based tracking algorithm by providing more accurate and robust tracking results. After testing with 100 sperm images, less misdetection of sperm has been observed from the results produced by the proposed ICMMS method. In future, the proposed method is expected to be implemented in analyzing male infertility.

This paper introduces a method to connect a camera, i.e., Pixy CMUcam5 as the vision detector of a robot soccer. The challenge point is to study how to connect this camera to CM-530 for Bioloid robot, since it is a low-prize compared with the embedded vision module of Havimo, which is a hardware platform of a Bioloid robot. In the genuine Bioloid robot, CM-530 works as the main processor. However, in this paper, CM-530 is used as the processor of actuators only, while the main processor is replaced by using Arduino micro controller. This method will be used for the learning material of robotics; thus, there are some topics should be observed, i.e., connection, data interpretation, and its implementation for robot soccer. In this paper, Pixy CMUcam 5 was confirmed that it can be used appropriately for robot soccer, especially for detecting ball, goalpost, opponent, and team mates based on color. Furthermore, this camera can also be used to interpret the distance of objects to determine the motion actions.

The change of appearance of the target object is one of important issue in visual tracking. It is because some factors such as camera motion, illumination change, motion change, occlusion, and size change are influenced to the object target during tracking. Recently, discriminative correlation filters (DCF) gave good results to handle these problems. Unfortunately, the DCF only works in the single-resolution features maps. In this paper, multi-scale color features are investigated to to solve this limitation. The multi-scale color features are implemented with correlation filter where it works in the continuous domain. In consequence of this reason, the implicit model of the target object is needed. So that, an interpolation is used to solve this problem. The output of this method is selected from the circular convolution response which has maximum value. Extensive experimental results on VOT2015 benchmark dataset which consists of 60 challenging videos show that the multi-scale color features based on correlation filter performs favorably against several state-of-the-art methods.

A complete decoder is one that guarantees to decode a received vector to its nearest codeword. For the design of an efficient complete decoding algorithm, storage demand and decoding complexity are two essential factors. Along this consideration, the Zero-Guards algorithm provides a significant improvement as the number of vectors required to be stored has been made much less than what is required by the conventional standard array decoding. When being applied to certain block codes, however, it may be inefficient when code length is short. At this background, a new step-by-step complete decoding algorithm for cyclic codes is proposed in this work. Based on a newly devised transfer function, our algorithm can achieve a better decoding efficiency than the Zero-Guards algorithm, while keeping a smaller number of vectors for most of the cyclic codes examined.
