    2nd place in the Competition for the best master's thesis organized by the Łódź Branch of the SEP in the 2018/2019 academic year.

    Supervisor: Marcin Kociołek


    Multipoint forces measuring systems are used in medicine more and more frequently. Their growing popularity is a result of the capability to measure a distribution of forces, which in many medical fields is a key factor in the search for any harmful deviations from normal state of an organism. However, multipoint force measurement systems in medical applications face many challenges. The precision of multipoint force measurement is another and often the most important challenge in systems whose task is to warn a physician about excessive force. The aim of this thesis was to design, build, launch and test a multipoint force measurement system. The aim of the study was achieved. Within the framework of the work, a force measuring system for two sensors was built. One with use of Flexiforce A301 sensor and the second with a strain gauge.

    Machine learning methods in application to automated determination of arterial input function for quantitative estimation of renal perfusion

    One of the most popular methods for renal perfusion quantification is DCE-MRI – Dynamic Contrast-Enhanced Magnetic Resonance Imaging. Thanks to the application of one of the various pharmacokinetic models, it could be used for image-based assessment of perfusion parameters. In any case, it is necessary to determine an arterial input function (AIF), i.e. the concentration of contrast agent in the aorta over time, supplying the tissue of interest in blood. It is usually performed manually, which leads to an increased error of this method. The aim of this dissertation is to present a possible method to automatize the determination of the AIF while eliminating the influence of the inflow artifact. The proposed procedure consists of two stages: the first is segmentation of the descending aorta by means of commonly used filters and a vascularization function; in the second stage, it uses a k-means clustering method to choose the region lying close to renal arteries and still not affected by the inflow artifact. Such a solution would increase the accuracy and reliability of image-based perfusion quantification methods. The proposed method was applied to real examinations of 10 healthy volunteers. Alongside each imaging series, an automatic segmentation of the aorta was performed to assess the reliability of the method discussed. The obtained GFR results were compared with standard methods other than image-based: iohexol clearance (the gold standard) and eGFR based on the MDRD equation and creatinine results. The precision obtained is similar to the one found in the literature. The agreement with iohexol-based values and eGFR is acceptable, especially taking into account that the agreement between the reference methods themselves is not ideal. The stated goal has been achieved – one of the first stages of the AIF determination has been automated, eliminating the error coming from the inflow artifact in DCE-MR images.

    Nowadays most of the applications of the stereovision are related to the mobile devices, especially in the field of computer vision systems and robotics. It is crucial to create efficient and robust algorithms that would allow their implementation in wide range of the environments. This thesis presents an efficient adaptive algorithm of stereo matching applied and optimized for mobile Graphics Processing Unit (GPU). It is a well known problem that most of the stereo vision algorithms are based on basic stereo matching algorithm that in most of the cases is the main factor of the computation complexity in solving the correspondence problem. The presented method introduces a novel approach to this problem by adaptively combining the cost function by using a very efficient small matching window and sparse accumulated windows similar to those applied in convolutional neural networks. Adaptability of this method is based on local characteristics of the images. Such a solution allows to compute disparity maps of subpixel precision both on highly textured areas of the image as well as on weakly matchable texture-less areas like walls and floor. The algorithm is very efficient computationally due to its design that is specially dedicated to a mobile GPU architecture. Keywords: Stereo vision, machine vision, mobile applications, disparity, depth map.

    1st honorable mention in the competition in the Competition for the best engineering diploma thesis organized by the Łódź Branch of SEP in the 2016/2017 academic year.


    The aim of the study was to analyze the activity of lower limb muscles during gait, stair ascent and treadmill exercise in diabetics with peripheral neuropathy and healthy persons. Gait analysis involved 10 control and 9 neuropathic subjects, stair negotiation analysis – 10 control and 7 neuropathic and treadmill exercise analysis – 7 participants in both groups. The electrical activity of six muscles was recorded bilaterally: rectus femoris, gluteus medius, tibialis anterior, peroneus longus, gastrocnemius lateralis and extensor digitorum. Time and space parameters were determined using two force plates and a motion capture system. Data was analyzed by the use of MATLAB software. A program embracing the double threshold method devised by Bonato and Knaflitz was designed. The durations of muscles activity were calculated as well as the fragment of movement cycle in the moment of the activation and deactivation of muscles. The data was analyzed in the SPSS software by means of independent-samples t-test. In gait reduced ankle mobility of diabetic neuropathic subjects was confirmed by earlier cessation of TA and GAL activity and reduced duration of EXD contraction. Reduced stabilization of hip was approved basing on reduced duration of GM activity and earlier activation of RF. In stair ascent the duration of GAL activity was longer suggesting reduced knee stabilization in diabetic patients with neuropathy. Prolonged activation of RF was detected confirming that reduced mobility of ankle is compensated by increased activity of hip flexor muscles. The results suggest presence of deviations in activity of lower limb muscles in subjects with diabetic neuropathy. Keywords: diabetic neuropathy, electromyography, lower extremity, activities of daily living.

    Numerical skeletonization of 3D binary object

    Piotr Zasiński

    1st honorable mention in the Competition for the best engineering diploma thesis organized by the Łódź Branch of SEP in the 2016/2017 academic year.

    Supervisor: prof. Andrzej Materka, Auxiliary promoter: dr. Marek Kociński


    This thesis explores the methods of extracting skeleton from three-dimensional binary discrete object. It aims to implement and, should it be possible, improve open-access algorithms of skeletonization of 3D binary objects. The algorithm is implemented as a console application written in C++. The core of the thesis is based on the work of Lee, Kashyap and Chu (LKC). The thesis describes some basic constructs of digital image processing. For the analysis of objects' topology the notion of Euler characteristic is explained. The algorithm suggested by Lee, Kashyap and Chu is meticulously investigated. Possible ways of realizing each particular step of the algorithm are presented. Attention is drawn to some potential disadvantages of the geometric conditioning used by Lee, Kashyap and Chu. Possible alterations are suggested, justified and tested. Created application is compared with openly available alternatives. Some errors in the results obtained using existing implementations are uncovered and pinpointed. The created solution appears to be free of those mistakes. What is more, the extracted skeletons exhibit a slight improvement in quality, which manifests in their more accurate length.
