Image Quality Control webinar

Huygens Deconvolution Wizard.
Since Huygens 21.10.1p0, the Deconvolution Wizard has also undergone some major changes. As of now, the deconvolution algorithm and SNR are automatically set to ensure optimal results for each single image. Still, they can be edited according to your preference, and the Deconvolution Preview option helps you with adjusting these settings by showing a fast preview of the result within a Region Of Interest (ROI). A slider and parameter field for adjusting the 'Acuity' have been introduced to further smoothen/sharpen the deconvolution result. This allows you to leave the SNR parameter to its real SNR value.(24 min)

Analyzing objects within other objects and object organization, using clusters and convex hull operations (24th of October 2023): This webinar focuses on the analysis of the organization or properties of objects, and the grouping of objects within other objects such as for example nuclei or cells. Huygens Object Analyzer can count and analyze the properties of objects within objects (cells, nucleus, organelles) in the other channel. The organization of objects can also be determined within just a single channel by clustering them using the Cluster Analyzer. And, geometric analysis of clusters is facilitated with the newly implemented convex hull option, which basically works like placing a rubber balloon around a cluster of objects. Convex hull based analysis also can aid the analysis of non-homogeneously stained objects, as is often the case with for example DAPI-stained nuclei. The ‘rubber balloon’/convex hull of the object then helps to fill the holes in the segmentation for the non-homogeneous staining. (18:20 min)
