In this paper, we present a robot toy designed to interact with the baby based on visual information captured by the camera. The robot toy navigates and keeps itself at a proper position to the baby and streams the video to the parents. The proposed robot toy not only can interact with the baby in a more natural way, but also help the parents make sure the baby is in a safe environment.
Shape-specific points are special data points invariant to translation, scaling, and rotation. The radius weighted mean (RWM) and the system center are two examples of shape-specific points. These points feature in contour registration, color quantization, and the detection of rotationally symmetric shape orientations. This study uses shape-specific points to cluster nonlinearly separable data into...
In this manuscript, a coin recognition system based on texture classification of the coin image is proposed. The proposed system consists of the training phase and the testing phase. In the training phase, the proposed system first identify the coin position in the image based on the generalized Hough transform. When the position is identified, the proposed system extract texture features of the coin...
In this manuscript, we propose a system which can automatically recognize the oyster racks in an aerial image. As the oyster racks are recognized, the volume of the oysters could thus be estimated and the price can be predicted in advance. Besides that, when a disaster such as a typhoon strikes on the offshore, the loss could also be estimated when the numbers of oyster racks before and after the...
The liquid crystal display (LCD) is widely used in various devices nowadays, for examples, mobile phones, digital cameras, and machine controllers. Among the components composing an LCD, the backlight module is one of the most important components because it provides a uniform light source for the display. In the current practice of backlight module inspection, a luminance colorimeter is used to examine...
In this paper, we propose a test-based assessment system running on top of the mobile devices. Both pad and phone devices are supported by the proposed system, though some functions on the pad are not provided on the phone due to the display size consideration. With the proposed system, students can take tests or review past tests on mobile devices, and teachers have no more the burden of marking...
In this manuscript, we propose to use the support vector regressions to inspect the backlight modules. In building the models of the support vector regressions, various combinations of parameters are examined and the accuracy are found to be similar. Experimental results show that the accuracy achieved by the proposed method is satisfactory.
In this manuscript, a system which automatically detects roads in the aerial image is proposed. The proposed method detects parallel lines in the image and calculates their centers as road centers. By examining color, width, and size-to-length ratio of detected road centers, the proposed method corrects some mislabeled objects. Besides that, the proposed method further extends road centers to make...
In this manuscript, a system which automatically measures the number of coins by using mobile devices is proposed. The proposed system converts the color space of captured image from RGB to Lab, applies feature-preserving clustering algorithm to quantize the transformed image plane, finds edges and circles in quantized image, and finally determines the number of coins. The experimental results show...
In this manuscript, a system which automatically detects internal defects in solar cell is proposed. The proposed system applies a bias flow to the solar cell, captures emissions of solar cell, and processes captured image to recognize the internal defects of the solar cell. The experimental results show that the proposed system can successfully detect the internal defect of solar cell which can not...
In this paper, we propose a luminance inspector which uses a CCD camera and neural network models to inspect multiple backlight modules at once. The proposed inspector can display the results at predetermined checked points in real time which is important for in-line quality check. The proposed inspector is more efficient compared to the traditional inspector which examines checked points one by one...
In this paper, a fast backlight module luminance inspection method is proposed. The proposed method inspects various backlight modules at once and all check points within the backlight modules are examined. Comparing to the traditional method which inspects one check point at a time, the proposed method is fast. The experimental results show that the proposed method usually yields satisfactory results.
