AI Technical Summary

Technical Problem

Conventional digital imaging systems fail to provide accurate multi-plane viewing of biological or chemical samples, leading to difficulties in analyzing cellular abnormalities due to flattened fused images that obscure depth information, and require excessive storage and transfer of multiple images.

Method used

Generate a pseudo-focus image by selecting best-focus pixels from multiple image planes, associating them with depth values, and applying Gaussian blur functions to simulate depth, allowing real-time multi-plane viewing without storing multiple images.

Benefits of technology

Enables accurate analysis of cellular structures by providing a sense of depth in digital images, reducing data storage needs and facilitating efficient transmission and examination of cytological specimens.

Abstract

Provision of digital imaging systems and methods [Solution] A method and system for providing multi-plane viewing of a digital image of an object without requiring viewing multiple images captured in multiple image planes. A pseudo-focus image is generated from a flattened fused image of a three-dimensional object. The fused image is generated by fusing multiple images captured in different focal planes of the object to form a through-focus image stack. The fused image contains the best-focus pixels resulting from each of the different image planes. A depth map is also generated from the multiple images, associating each best-focus pixel with a pixel depth value. A point of interest (POI) is selected from the image planes. The pseudo-focus image is then generated by using the fused image and the pixel depth map to generate a blurred focus value for each best-focus pixel based on the focal offset of each pixel from the POI.
