Image Reconstruction in Third-Harmonic Generation Microscopy
Type: Master (semester project) Supervisor: Vasiliki Stergiopoulou (LCAV, Galatea) Contact: [email protected] Project Context: Third harmonic generation (THG) microscopy is a non-fluorescent multiphoton technique that enables three-dimensional imaging of refractive index differences. To obtain an accurate reconstruction, we tackle an optimization problem, minimizing a weighted combination of two terms. The first term ensures that reconstructions align (…)
Local maxima estimation of gradients to speed up a convex optimization algorithm
Contact: Adrian Jarret (LCAV) Synopsis: Discover the Frank-Wolfe algorithm for convex optimization with sparse priors, contribute to the development of a fast polyatomic variant, find local maxima on a 2D image, simulate image reconstruction for radio astronomy. Level: Bachelor – Master (semester project) Sections: IC Description: The LASSO problem [1] is a convex optimization problem (…)
Composite Reconstruction of Images in Radio Astronomy
Contact: Adrian Jarret (LCAV) Synopsis: Reconstruction of radio astronomy images as a sum of components from two dictionaries, using linear inverse problems with a composite penalty. Level: Master Sections: IC Description: One of the main challenges in radio astronomy is to reconstruct an image of the sky from noisy interferometric measurements of the radio waves (…)
Automatic Flat Colouring
Contact: Michalina Pacholska Synopsis: Create an automatic tool for flat comic colouring. Level: Master Students Description: On the left is a line-art image [0]. When creating the comic, the artists will create line-arts for every panel of the comic, that will have to be coloured. It’s often more convenient to add so-called flat colours first, shown (…)
