Welcome to my homepage. I am currently working at post-doc position in the Biomedical Imaging Algorithms (BIA) group which is led by Prof. Jan Kybic. The group is part of the Center for Machine Perception (CMP), at the Department of cybernetics, Faculty of electrical engineering of the Czech Technical University in Prague.

Multiple Instance Learning (MIL) for bone cancer detection (current)
One of the characteristics of multiple myeloma is the propagation of the disease into the bone marrow tissue. In clinical routine, the extent of bone marrow tissue infiltration is used for staging purposes. Since a thorough and complete annotation of all infiltrations is hard to accomplish, the problem of automatic infiltration detection can be formulated as a multiple-instance learning task.
Generalized-MIL Problems
The standard MIL formulation is based on two (complementary) conditions -- the positive identifiability and negative exclusion. The later says, that in a negative bag, all instances are negative and conversely, for the first one, that a single positive instance already makes the whole bag positive.The standard MIL formulation is not robust against a single false-positive instance, which can easily occur in noisy conditions. A generalized MIL formulation considers the number of positive instances, that decides wheter the global label is positive or negative is a parameter. We have shown (SPIE MI 2018), that this parameter can be efficiently learned during the training phase.

(Pre)processing of diffusion-weighted MR Images
One of the crucial tasks for robust analysis of diffusion-weighted data is the task of correcting for motion and acquisition distortion. To achieve a robust correction scheme I have focused on developing an image registration method that can consider and efficiently combine the information from available image metrics. In the novel, multi-objective correction scheme, a local optimization method by traditional pair-wise image registration is considered together with a global, particle-swarm optimization method.Related publications
