The enhancement of lung nodules in chest radiographs plays an important role in computer-aided diagnosis, and is more useful for doctor observing and analyzing. In this paper, we introduce a parameterized logarithmic image processing (PLIP) method based on Laplacian of Gaussian (LoG) filtering to enhance lung nodules in chest radiographs. This method combines the advantages of both algorithms which...
A self-adaptive road detection method based on vision and cluster analysis is proposed for automatic guided vehicles. Based on the K-means algorithm, an automatic sample selection method is developed — while moving, the vehicle automatically selects new road samples and takes cluster analysis at a specified time interval to get the latest road features. Verified by experiments on campus roads, the...
A new airport runway extraction method is put forward. Firstly, it is utilized the fuzzy enhancement arithmetic to highlight the runway in the image; And then using canny operator for edge detection; Use mathematical morphology opening which can make some of the curved edge in the image broken down into smaller straight edge; Finally, we can obtain the runway by marking the location of the edge and...
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...
