Among others, I will be talking about patterns in multidimensional data, topological idea in object tracking, applications of cohomology generators in avoiding obstacles and the common ideas between rectangular CW complexes and irregular graph pyramids. I hope the talk will trigger out a long discussion and some paper and common application of PRIP and Kraków group for some common project.

In the first part a quality measure for evaluating the performance of segmentation algorithms is presented. This discrepancy method is based on object-by-object comparison of a segmented image (machine segmentation) versus ground-truth segmentation (reference image). The error measure takes into consideration the interior of the object and eliminates the inconveniences that appear in the case of the concave objects. A weighted shape fitting score is used: the score of the segmented contour is enhanced by a factor which indicates the similarity between these two curves. The second part contains automatic segmentation techniques for detecting cell nuclei in images taken from tissues with colon carcinoma. The region growing method is used to obtain accurate background detection. New approaches are proposed to detect the separation areas between clustered/touching cell nuclei. These regions are validated based on their link with the background. The watershed segmentation algorithm followed by a merging criterion is used to completely delimit the nuclei boundaries.

An existing algorithm using simplicial complexes is adapted to the setting of cubical complexes. The proposed approach enables efficient application of persistent homology in domains where the data is naturally given in a cubical form. By avoiding triangulation of the data, we significantly reduce the size of the complex. We also present a data-structure designed to compactly store and quickly manipulate cubical complexes. By means of numerical experiments, we show high speed and memory efficiency of our approach. We compare our framework to other available implementations, showing its superiority. Finally, we report persistent homology results for selected 3D and 4D data sets.
