1. 1. Symmetry in a free boundary problem

   University essay from KTH/Matematik (Avd.)

   Author : Seuri Basilio Kuosmanen; [2023]
   Keywords : Analysis of PDEs; Bernoulli-type boundary condition; free boundary problem; Laplacian operator; method of moving planes; symmetry; Analys av PDEs; Bernoulli-typ randvärde; frirandsproblem; Laplaceoperatorn; moving-plane metoden; symmetri;

   Abstract : We consider a variational formulation of a Bernoulli-type free boundary problem for the Laplacian operator with discontinuous boundary data. We show the existence of a weak solution to the problem. Moreover, we show that the solution has symmetry properties inherited by symmetric data. READ MORE

3. 2. Click me: thumbnail extraction for fashion videos : An approach for selecting engaging video thumbnails based on clothing identification, sharpness, and contrast.

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

   Author : Isabel Redtzer; [2023]
   Keywords : Thumbnail Extraction; User Engagement; Object Identification; YOLO; Laplacian Operator; Miniatyrbildsextraktion; Användarengagemang; Objektidentifiering; YOLO; Laplaceoperatorn;

   Abstract : Video thumbnails are essential to represent the content and summary of a video. This thesis proposed a thumbnail extraction approach for fashion videos based on the presence of clothing items, sharpness, and contrast. Furthermore, this thesis investigated how the proposed thumbnail selection method performed concerning user engagement. READ MORE
