Automatic Triage of Photo Collections

Status: taken Supervisor: Sebastian Zambanini Problem Statement Photo triage is the process of grouping similar photos of a large collection and finally selecting the most preferred one in each group. Especially the selection of “the” best photo of a group is challenging as the relevant image features are not obvious to identify and heavily scene-dependent. … Continue reading Automatic Triage of Photo Collections

Shadow Removal in Satellite Images

Status: available Supervisor: Sebastian Zambanini Problem Statement Shadows cast in remote sensing images complicate their analysis due to the low contrast in the poorly illuminated image regions. Shadow removal/compensation methods aim at automatically reducing shadow effects, either by a physical or learning-based  model. Goal The goal of this work is to explore and examine methods … Continue reading Shadow Removal in Satellite Images

Person Detection and Data Diversity

Status: available Supervisor: Roman Pflugfelder Problem Statement Visual person detection is a foundational building block in almost every application from pedestrian detection in surveillance and autonomous driving, to person perception in robotic systems, to human localisation in user-centric computing. Person or pedestrian detection has made a significant leap in the last years, by re-discovering the … Continue reading Person Detection and Data Diversity

Vehicle Detection in Satellite Videos

Status: available Supervisor: Roman Pflugfelder Problem Statement The robust detection of specific objects such as buildings, ships and road networks has been an important challenge in remote sensing and satellite image processing. Since 2014, a new generation of satellites allow to extend the number of object categories to smaller objects such as vehicles, aircraft and many … Continue reading Vehicle Detection in Satellite Videos

Evaluierung von Person Tracking Algorithmen auf Tiefendaten

Status: vergeben Supervisors: Rainer Planinc, Sebastian Zambanini Problemstellung Tiefendaten vereinfachen das Problem des Person Trackings in Videos durch eine deutlichere Unterscheidbarkeit von Vorder- und Hintergund der Szene. In den letzten Jahren wurden zahlreiche Methoden vorgestellt, die aber alle für bestimmte Szenarien gedacht sind und auch dahingehend evaluiert wurden. Es gibt jedoch eine Vielzahl von Parametern, … Continue reading Evaluierung von Person Tracking Algorithmen auf Tiefendaten

Normalized Flowcytometry Representation of Blood Cell Populations of Children affected by Acute Leukaemia

Supervision Michael Reiter, Roxane Licandro Problem Statement Acute Leukaemia is a disease induce by genetic alterations of blood progenitor cells, which influences the blood generation process (haematopoiesis) and leads to the proliferation of undifferentiated (leukaemic) cells. Flow CytoMetry (FCM) measurements are used to reliably assess these cancer cells (blasts) and to quantify their ratio to … Continue reading Normalized Flowcytometry Representation of Blood Cell Populations of Children affected by Acute Leukaemia

Dermoscopic Image Analysis by Deep Learning

Status: available Supervisor: Michael Reiter, Christopher Pramerdorfer The purpose of this work is to classify sequences of dermatoscopy images as “changing” or “not changing”. The term “change” refers to a depicted mole or skin lesion, and a given sequence should be classified as “changing” if the depicted mole changes in a form that indicates  a tumor, not simply … Continue reading Dermoscopic Image Analysis by Deep Learning

Deep-Learning for Gender Classification/Age Estimation

Status: available Supervisor: Martin Kampel Problem Statement Automatically detecting the gender of a person or estimating his/her age is valuable in many fields of work. In the area of computer vision exist a variety of possible approaches, mostly based on machine learning, to accomplish this task. A higher complexity arises due to the claim to … Continue reading Deep-Learning for Gender Classification/Age Estimation

Pattern Matching of Footwear Impressions

Status: available Supervisor: Manuel Keglevic Problem Statement One of the most frequently secured types of evidence at crime scenes are footware impressions. Identifying the brand and model of the footware can be crucial to narrowing the search for suspects. This is done by forensic experts by comparing the evidence found at the crime scene with … Continue reading Pattern Matching of Footwear Impressions
