Image Reconstruction in Third-Harmonic Generation Microscopy

Ongoing Projects

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

Ongoing Projects

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

Ongoing Projects

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

Ongoing Projects

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 (…)
