Vehicle tracking and speed estimation for traffic surveillance
… tools for thresholding, filtering and blob analysis. Optical flow was the image processing technique used to determine the moving vehicles. A median filter was used to remove salt and pepper noise from the thresholded image. Combinations of several morphological operations were used to …

Development of a vision-based local positioning system for weed detection
… algorithms were based respectively on a stripe analysis, a blob analysis, a linear regression and the Hough Transform. The last two also included an edge-detection step. Images of parallel line patterns representing crop rows were collected at different angles, with and without weed-simulating …

Studies of Edge Fluctuations of Negative Triangularity Plasma on TCV using a New Gas-Puff Imaging Diagnostic
… confinement fusion devices requires thorough analysis of edge plasma turbulence, which plays a key role in dealing with the exhaust heat and particle loads on the wall materials. Edge plasma turbulence differs depending on various plasma conditions including plasma shape, e.g., the …
