Despite a rapid rise in the quality of built-in smartphone cameras, their physical limitations - small sensor size, compact lenses and lack specific hardware, impede them to achieve results DSLR cameras. In this work we present an end-to-end deep learning approach that bridges gap by translating ordinary photos into DSLR-quality images. We propose translation function using residual convolutional neural network improves both color rendition image sharpness. Since standard mean squared loss...

Low-end and compact mobile cameras demonstrate limited photo quality mainly due to space, hardware budget constraints. In this work, we propose a deep learning solution that translates photos taken by with capabilities into DSLR-quality automatically. We tackle problem introducing weakly supervised enhancer (WESPE) - novel image-to-image Generative Adversarial Network-based architecture. The proposed model is trained under weak supervision: unlike previous works, there no need for strong...

As the popularity of mobile photography is growing constantly, lots efforts are being invested now into building complex hand-crafted camera ISP solutions. In this work, we demonstrate that even most sophisticated pipelines can be replaced with a single end-to-end deep learning model trained without any prior knowledge about sensor and optics used in particular device. For this, present PyNET, novel pyramidal CNN architecture designed for fine-grained image restoration implicitly learns to...

Bokeh is an important artistic effect used to highlight the main object of interest on photo by blurring all out-of-focus areas. While DSLR and system camera lenses can render this naturally, mobile cameras are unable produce shallow depth-of-field photos due a very small aperture diameter their optics. Unlike current solutions simulating bokeh applying Gaussian blur image background, in paper we propose learn realistic focus technique directly from produced cameras. For this, present...
