1Quantity of substance
If conventional compression methods (JPEG, JPEG 2000) are applied to three-dimensional microscopic images, then some data reduction is achieved, but compression efficiency is insufficient and processing time is excessively long
Solution Approach 1:
The three-dimensional image data is divided into multiple two-dimensional image layers corresponding to different focal planes. Each layer is processed independently through the video compression pipeline, enabling parallel processing and reducing overall compression time while maintaining efficient compression ratios.
Solution Approach 2:
A focal plane moving mechanism is introduced as an intermediary component between the microscope and imaging unit. This mechanism enables systematic acquisition of multiple focal plane images, which are then processed as discrete layers through the video compression system, achieving both high compression efficiency and acceptable processing speeds.
2Quantity of substance
If high compression ratios are achieved using advanced compression techniques, then data storage requirements are reduced, but processing complexity and cost increase
Solution Approach 1:
The system dynamically adjusts compression parameters and focal plane sampling intervals based on the specific characteristics of the microscopic specimen and imaging conditions. This adaptive approach optimizes the balance between compression ratio and processing complexity, achieving high compression without requiring overly complex system configurations.
Solution Approach 2:
The invention changes key parameters including focal plane interval, image acquisition timing, and compression settings to optimize the compression process. By adjusting these parameters based on specimen characteristics, the system achieves high compression ratios while controlling processing complexity and computational cost.
3Loss of information
If three-dimensional imaging is performed by capturing multiple focal planes, then comprehensive specimen information is obtained, but data volume increases significantly
Solution Approach 1:
The invention extracts and processes only the essential information from each focal plane layer through video compression techniques. By applying compression algorithms that identify and retain significant features while discarding redundant data, the system preserves three-dimensional specimen information while dramatically reducing the total data volume requiring storage and transmission.
