  1. 11. Estimating the probability of event occurrence

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alexandre Guinaudeau; [2019]
    Keywords : ;

    Abstract : In complex systems anomalous behaviors can occur intermittently and stochastically. In this case, it is hard to diagnose real errors among spurious ones. These errors are often hard to troubleshoot and require close attention, but troubleshooting each occurrence is time-consuming and is not always an option. READ MORE

  3. 12. Pixel-Based Algorithms for Data Analysis in Digital Pathology : Data Analysis of the BOMI2 Redox Dataset, A Step Away From Cell Segmentation Dependant Methods

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Michael Wallgren Fjellander; [2019]
    Keywords : Digital Pathology; Image Analysis; Algorithms; Cell Segmentation; Pixel-based Methods; Cancer; Knee Point;

    Abstract : In this project report a novel pixel-based approach to digital pathology is proposed. The algorithm directly decides the class of single pixels in an image without needing the larger context of neighbouring pixels. READ MORE

  4. 13. A Gaussian Mixture Model based Level Set Method for Volume Segmentation in Medical Images

    University essay from Linköpings universitet/Beräkningsmatematik; Linköpings universitet/Tekniska fakulteten

    Author : Grayson Webb; [2018]
    Keywords : Probablistic level set methods; Gaussian mixture models; image segmentation; volume segmentation; medical images;

    Abstract : This thesis proposes a probabilistic level set method to be used in segmentation of tumors with heterogeneous intensities. It models the intensities of the tumor and surrounding tissue using Gaussian mixture models. READ MORE

  5. 14. Classification of skin pixels in images : Using feature recognition and threshold segmentation

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Emil Samuelsson; [2018]
    Keywords : ;

    Abstract : The purpose of this report is to investigate and answer the research question: How can current skin segmentation thresholding methods be improved in terms of precision, accuracy, and efficiency by using feature recognition, pre- and post-processing? In this work, a novel algorithm is presented for classification of skin pixels in images. Different pre-processing methods were evaluated to improve the overall performance of the algorithm.

  6. 15. Automatic Tissue Segmentation of Volumetric CT Data of the Pelvic Region

    University essay from Linköpings universitet/Medicinsk informatik

    Author : Julius Jeuthe; [2017]
    Keywords : Image segmentation; Computed tomography; Pelvic region; Threshold segmentation; Region growing; Histogram matching; Atlas segmentation; Morphon;

    Abstract : Automatic segmentation of human organs allows more accurate calculation of organ doses in radiationtreatment planning, as it adds prior information about the material composition of imaged tissues. For instance, the separation of tissues into bone, adipose tissue and remaining soft tissues allows to use tabulated material compositions of those tissues. READ MORE
