2017 3rd International Conference on Pattern Recognition and Image Analysis (IPRIA) > 56 - 61

2017 3rd International Conference on Pattern Recognition and Image Analysis (IPRIA)

This article introduces a new technique to reduce the parameters of the Circular Hough Transform (CHT). CHT is a well-known technique to locate circles in an image. One of the main drawbacks of CHT is its three-dimensional parameter space (location and radius of the circle) which makes this algorithm not memory efficient. In this article, based on morphological operations, we reduce this parameter...

Methods > 2017 > 115 > C > 91-99

In this paper we propose a workflow to detect and track mitotic cells in time-lapse microscopy image sequences. In order to avoid the requirement for cell lines expressing fluorescent markers and the associated phototoxicity, phase contrast microscopy is often preferred over fluorescence microscopy in live-cell imaging. However, common specific image characteristics complicate image processing and...
