In order to merge multispectral image and high-resolution panchromatic image and to improve abilities of information analysis and feature extraction, we study discrete multiwavelet analysis on image data and give a fusion method in pixel level by means of discrete multiwavelet transform in this paper.

A new type of pixel-level on-chip analog-to-digital conversion circuit for infrared focal plane array(IRFPA) has been proposed based on serial single-slope integration.

This paper figured the ideas and core contents of remote sensing data fusion based on the universal theoretical framework for pixel-level remotely sensed data fusion,which would extend the pixel-level framework to feature-level and then decision-level step by step,focusing on the development of a new Universal theoretical system for remotely sensed data fusion.

There are many pixel-level fusion methods for remote sensing images,but the differences of those are ambiguous because of lacking a unique description,which makes it difficult to apply image fusion purposefully.

The generalized model characterizing most remotely sensed data pixel-level fusion techniques is very important for theory analysis and application.
