MARC MASIAS defends his PhD thesis: “Automatic source detection in astronomical images”

This thesis is focused on the automatic detection of sources (objects) in astronomical images. These sources are something that suggests the presence of an astronomical object such as stars, galaxies, gas, dust or cosmic rays. The use of automatic algorithms to perform such a task becomes of great importance in the astronomical field because of the increasing amount of data and the inefficiency and inaccuracy of manual inspection.   In the first place, we exhaustively analyze the state of the art on this topic, presenting a new classification of techniques and pointing out their main strengths and weaknesses. A complementary…

Konstantin Korotkov defends his PhD thesis “Automatic change detection in multiple pigmented skin lesions”

Malignant melanoma is the rarest and deadliest of skin cancers causing three times more deaths than all other skin-related malignancies combined. Fortunately, in its early stages, it is completely curable, making a total body skin examination (TBSE) a fundamental procedure for many patients. During TBSE, dermatologists look for pigmented skin lesions (PSLs) exhibiting typical melanoma signs as well as PSLs undergoing the rapid changes characteristic of cancer. Accompanied by clinical and dermoscopic baseline photography, a TBSE can be very tedious and time-consuming, especially for patients with numerous lesions. In addition, establishing correct body-to-image and image-to-image lesion correspondences can be extremely…
