Reliability and cost are two important driving factors in the development of wind energy. Automation and digitalization of operation and maintenance (O&M) procedures help to increase turbine reliability and reduce the levelized cost of energy (LCOE). Here, we demonstrate a novel method, coined as AQUADA, which may change the current labor‐intensive and operation‐interfering blade inspection by...
Video summarization usually refers to produce a summary preserving essential content of the original video. Many existing methods have been developed to select representative frames by a dictionary learning model, which have led to a state-of-the-art performance. However, learning dictionary without considering relationship between samples of the original data space would lead to imprecise representation...
The scene perception is a process of getting content and meaning of scene from a group of objects that have specific spatial relationships. Therefore, the research of the processing based on the scene perceived features is essential for image understanding and scene recognition. Cognitive science research results show that the cognitive process of visual information processing using a bottom-up and...
In the paper an face location and eye detection method is proposed based on active infrared source system, which is to solve the problems of pupil threshold segmentation according to from coarse and fine strategy. This method use bright pupil and dark pupil difference scheme. Firstly, we collect a lot of dark images to train classifiers make use of Haar features, boosting them to be a strong classifiers...
In this paper, a novel scene retrieval method has been proposed. Under this framework, homogeneous color regions are detected and then described by color moment invariants. Different from most existing methods, color and spatial information are combined as the uniform descriptor to capture the image property. Moreover, the image descriptor in our method has alterable data structure, whose size is...
Moving object detecting is one of the current research hotspots and is widely used in fields such as computer vision and video processing. The study on image processing toolkit using computer language Matlab was conducted to perform moving object detecting technical processing on video images. First, video pre-processing steps such as frame separation, binary operation, gray enhancement and filter...
