I2SB, which stands for Image-to-Image Schrödinger Bridge, is a project that addresses the challenge of image-to-image translation with a novel approach.


The I2SB (Image-to-Image Schrödinger Bridge) project introduces an innovative method in the field of computer vision, specifically within the area of image-to-image translation. This technique is noteworthy for its use of the Schrödinger Bridge problem, a concept derived from the realms of mathematics and physics. The Schrödinger Bridge problem focuses on determining the most efficient path for transitioning between two probability distributions over a given timeframe, inspired by principles from quantum mechanics and stochastic processes.

In the context of I2SB, this mathematical framework is applied to the domain of image processing. The goal is to transform one image into another, not through traditional means, but by considering the images as manifestations of underlying probability distributions. This perspective allows I2SB to seek the optimal transformation pathway that respects the inherent statistical properties of the images. By doing so, the project endeavors to achieve translations that are not only more accurate in replicating details and structures but also more realistic in terms of preserving the natural characteristics and textures of the source and target images.

The significance of I2SB lies in its potential to overcome limitations of existing image-to-image translation techniques, which often struggle with maintaining realism or fidelity, especially in complex scenes or when translating between significantly different image domains. Through its novel application of the Schrödinger Bridge framework, I2SB offers a promising direction for enhancing the quality and applicability of image translation technologies, with potential implications for a wide range of applications, from artistic image generation to practical tasks in medical imaging, surveillance, and beyond.
