It is a trend to use information technology to lead the development of modern agriculture. The IntelliSense Internet of Things will be an important support for intensive, high-yield, high-quality, efficient, ecological security agriculture. In this paper, we give solutions and key technologies of facilities agriculture based on the Internet of Things… (More)
In this paper, a novel adaptive bandwidth object tracking using sparse approximation is proposed in mean shift framework. In this framework, occlusion, illumination and other challenging issues are addressed seamlessly in real time through bandwidth approximation. To find the tracking target at a new frame, a two step method is used iteratively to find the… (More)
This paper presents a new method to calculate the Euclidean distance among pixels by taking the gray value of a pixel as the distance weight. The energy distribution curve extracted from coherent scatter images with this method. The signal value of the curve has been intensified and the noise has been reduced effectively.
There are many visual tracking algorithms that are based on sparse representation appearance model. Most of them are modeled by local patches with fixed patch scale, which make trackers less effective when objects undergone appearance changes such as illumination variation, pose change or partial occlusion. To solve the problem, a novel appearance… (More)
In this paper, we propose a new image and video sequences reconstruction approach, where the Newton-Thiele’s vector valued rational interpolation is combined with the sparse principal component analysis. Through observation of the degraded model, the reconstruction scheme is performed by two steps. Firstly, the sparse principal component analysis and the… (More)
Based on the latest international CDIO engineering education concept, the correspondence relationship between the four abilities of the Java language teaching target and the CDIO education project idea is analyzed. The Java teaching method based on CDIO engineering education idea is discussed. This teaching method is mainly from the aspects of theoretical… (More)
