We present a novel image superpixel segmentation approach using the proposed lazy random walk (LRW) algorithm in this paper. Our method begins with initializing the seed positions and runs the LRW algorithm on the input image to obtain the probabilities of each pixel. Then, the boundaries of initial superpixels are obtained according to the probabilities and the commute time. The initial superpixels...
Lateral inhibition is a technique to enhance the sharpness of images, which is developed from Hartline's research on sensory inhibition. Conventional lateral inhibition operates on the entire image like high-pass filter, which also strengthens noise besides edges. Thus this paper proposes an adaptive lateral inhibition based on the features of the image's color distribution detected by improved Ruzon...
With the enhancement of mobile devices features, to reduce the power consumption and extend the battery duration is a big challenge. To reduce power consumption and enhance the image display quality in the mobile devices, a novel structure of Multi-blocks Light Guide Plate (LGP) in the edge-type backlight module is proposed in this paper. The novel structure of LGP limits the backlight in one block...
The random walker method [1] has many nice characteristics for 3D image segmentation. However, it is computational expensive and slow due to a massive linear system to be solved. In this work, we take advantage of the probabilistic output from the random walker method applied to a small downsampled image. By using the original image and seeds information, a novel edge-preserving method is introduced...
In order to achieve fast and accurate collision detection of rigid body, this paper presents a continuous collision detection algorithm based on interval interpolation and static K_DOPs detection technique. This algorithm uses interval interpolation technique to obtain the polygonal lines which approximate the motion trajectory of rigid bodies, and then conducts the collision detection during the...
This paper presents a novel markerless augmented reality based piano teaching system, which tracks the real keyboard of piano naturally. Following the virtual hands augmented on the keyboard, beginners of piano can practice playing piano. Instead of the marker in traditional AR system, the geometrical parameters of the piano keyboard are detected to calculate the transformation matrix from keyboard...
Attractiveness of social network analysis as a research topic in many different disciplines is growing in parallel to the continuous growth of the Internet, which allows people to share and collaborate more. Nowadays, detection of community structures, which may be established on social networks, is a popular topic in Computer Science. High computational costs and non-scalability on large-scale social...
Efficient and reliable image segmentation & identification is the basis of scientific crop management and a key technology for precision agriculture. This paper introduces an image segmentation algorithm based on the fusion of infrared and visible images. First of all, the fusion algorithm, which is based on the second-generation Curvelet transformation, was used to fuse the infrared and visible...
Hough transform (HT) is a well-established method for curve detection and recognition due to its robustness and processing capability. Being the core principle, voting principle needs to find the max voting rate, which makes it impossible to detect many targets from single image synchronously. In this paper, an improved Hough transform algorithm which combines with clustering is presented. The algorithm...
