Iaro Melekhov

I am an Applied Scientist at Amazon. Previously, I did a postdoc and completed a PhD at Aalto University in Juho Kannala's research group.

During my PhD, I was a research intern at Niantic Labs (London) under the supervision of Prof. Gabriel Brostow and Dr. Daniyar Turmukhambetov. Before this, I spent 6 months in Cambridge, UK working on visual perception algorithms for autonomous cars and having fun at Wayve. I also did a research visit to Marc Pollefeys' Computer Vision and Geometry Group in the Department of Computer Science at ETH Zurich.

	A Dataset for Semantic Segmentation in the Presence of Unknowns Zakaria Laskar, Tomáš Vojíř, Matej Grcić, Iaroslav Melekhov, Shankar Gangisetty, Juho Kannala, Jiri Matas, Giorgos Tolias, C.V. Jawahar CVPR*, 2025 paper / code We propose a novel anomaly segmentation dataset, ISSU, that features a diverse set of anomaly inputs from cluttered real-world environments.
	Differentiable Product Quantization for Memory Efficient Camera Relocalization Zakaria Laskar, Iaroslav Melekhov, Assia Benbihi, Shuzhe Wang, Juho Kannala ECCV, 2024 paper / project page / code We propose a differentiable product quantization layer to address the memory efficiency of the camera relocalization pipeline.
	DN-Splatter: Depth and Normal Priors for Gaussian Splatting and Meshing Matias Turkulainen, Xuqian Ren, Iaroslav Melekhov, Otto Seiskari, Esa Rahtu, Juho Kannala WACV, 2025 paper / project page / code We extend 3D Gaussian splatting with depth and normal cues to tackle challenging indoor datasets and showcase techniques for efficient mesh extraction.
	ECLAIR: A High-Fidelity Aerial LiDAR Dataset for Semantic Segmentation Iaroslav Melekhov, Anand Umashankar, Hyeong-Jin Kim, Vladislav Serkov, Dusty Argyle CVPR Workshops, 2024 paper / project page / code We introduce ECLAIR, a diverse and high-fidelity aerial LiDAR dataset for point cloud semantic segmentation.
	Digging Into Self-Supervised Learning of Feature Descriptors Iaroslav Melekhov, Zakaria Laskar, Xiaotian Li, Shuzhe Wang, Juho Kannala 3DV, 2021 paper / project page / code We show how to use unsupervised learning to optimize a CNN-based local descriptor that is robust to illumination changes and competitve with its fully-supervised counterparts.
