In this tutorial I am going to show you how to use Image Object Smoothing, an image object manipulation tool that is helpful to refine shapes. Especially I will […]

Region of Interest If a simple rectangle is not suitable to enclose a region of interest (ROI) or to split the image for specialised image segmentations, here is a quick […]

Topological skeleton in LemnaGrid: Part IV In a previous post of mine I explained how to use Corn Leaf Segmenter to detect leafs and to measure leaf angles. In this […]

This week I wanted to repeat the VIS top image segmentation few days ago. It also suddenly dawned on me. When facing the image segmentation task, we usually think of […]

LemnaGrid is a platform for image processing and analysis. It uses Ipp, opencv, and other libraries as backend along with propriatory algorithms and provides graphical interface to the user to […]

Image segmentation on the basis of a HSI color image The ‘HSI to grey converter’ is a useful LemnaGrid tool to convert an RGB image into a more human intuitive […]

Topological skeleton in LemnaGrid: Part V

In the fifth part of our series we will build another grid application to measure leaf angle in corn but use another grid device. Specifically […]

Topological skeleton in LemnaGrid: Part III The ability of LemnaGrid to create a topological skeleton from a shape, allows us to split an imaged plant into its larger constituents: leaf/branch […]
