Nuclei segmentation via sparsity constrained convolutional regression [PDF]

open access: yes2015 IEEE 12th International Symposium on Biomedical Imaging (ISBI), 2015
Automated profiling of nuclear architecture, in histology sections, can potentially help predict the clinical outcomes. However, the task is challenging as a result of nuclear pleomorphism and cellular states (e.g., cell fate, cell cycle), which are compounded by the batch effect (e.g., variations in fixation and staining). Present methods, for nuclear

Interactive Natural Image Segmentation via Spline Regression [PDF]

open access: yesIEEE Transactions on Image Processing, 2009
This paper presents an interactive algorithm for segmentation of natural images. The task is formulated as a problem of spline regression, in which the spline is derived in Sobolev space and has a form of a combination of linear and Green's functions. Besides its nonlinear representation capability, one advantage of this spline in usage is that, once ...
