The different kinds of diseases and insect pests of the 5 different crop leaves are used as the research object. Through the gray processing of the images, the removal of the unrelated background, the image segmentation, and the filling of the pixels of the crop disease and insect pests, ...
Reconstruction of segmentation and 3D volume in medical imaging is a method that enables diagnostic optimization, and can also facilitate the specialist in qualitative and quantitative research. In diverse uses such as modeling, quantitative analysis and image-guided surgery, it's an essential step. ...
In order to improve the real-time tracking of seam ultrasonic inspection,two image segmentation methods are applied to two different seam tracking systems,which are white line tracking and laser tracking.In the first method,the target edge in inspecting image is extracted by edge detection of Hough...
Convolution operator-based neural networks have shown great success in medical image segmentation over the past decade. The U-shaped network with a codec structure is one of the most widely used models. Transformer, a technology used in natural language
Using a random forest, we first generate multiple partitions of the same input space, one per tree. The partitions from all trees are merged by i... F Perbet,Bjrn Stenger,A Maki - 《Bmvc》 被引量: 27发表: 2009年 加载更多研究点推荐 image segmentation 站内活动 ...
the segmentation process. This is a major advantage in contrast to other approaches (like supervised methods) which either need a large training set or significant amount of expert or apriori knowledge. RL方法的优点在于可以用较少的样本来进行训练,并且能得到额外的知识,而监督学习通常需要较大的训练...
Deformable template models are valuable tools in medical image segmentation. Current methods elegantly incorporate global shape and appearance, but can not cope with localized appearance variations and rely on an assumption of Gaussian g...

Graph based semi-supervised learning (GSL) method runs slowly because of the need of much time to construct a neighbor graph. This paper presents a hash graph based semi-supervised learning (HGSL) method, which can search neighbors by locality sensitive
The algorithm can significantly reduce the training time of support vector machine and large-capacity data set and has good generalization performance. In order to verify the application of the algorithm,this paper selects relative color images from Berkeley image segmentation data set BSDS500 and ...
