The requirement for suitable ways to measure the distance or similarity between data is omnipresent in machine learning, pattern recognition and data mining, but extracting such good metrics for particular problems is in general challenging. This has

There has been shown a strong association between the integrity of the inner/outer segment (IS/OS) junction and the visual acuity in various retinal diseases. We propose an automated method for IS/OS defect detection in optical coherence tomography i

Automatic recognition of sign language gestures is becoming necessary with an increased interest into human-computer interaction in sign language as well as automatic translation from sign language. Most of the research on sign language recognition f

The concept of building 3D models, known as 3D reconstruction, already exists since the last few decades. However, by manually aligning the objects during acquisition phase does not guarantee that the output, the 3D models, will be perfectly aligned

In this paper, we propose a novel multi-view method for surface reconstruction from matched line segments with applications to robotic mapping and image-based rendering. Starting from 3D line segments and poses obtained via Line-SLAM, we project segm

The growth of human bones forms a major problem when automatically segmenting orthopedic radiographs. Any template-based segmentation methods fails to fully capture these non-linear developments. However to extract orthopedic measurements or the bone

In this paper we propose improvements to particle streak tracking. The main focus is an improved segmentation method considering local image statistics combined with classic edge detection and removal of the scene background, which at the same time s
