This paper presents a new approach to smart sensor system design for real-time remote sensing. A combination of techniques for image analysis and image compression is investigated. The proposed algorithms include: (1) a fractional discrimination function for image analysis, (2) a comparison of effective algorithms for image compression, (3) a pipeline architecture for parallel image classification and compression on-board satellites, and (4) a task control strategy for mapping image computing models to hardware processing elements. The efficiency and accuracy of the proposed techniques are demonstrated throughout system simulation.

A compression method for good visual quality is proposed in this paper. It is based on JPEG-XR. The visual quality is measured by structural similarity (SSIM). By some image compression experiments, the minimum SSIM is determined in a manual way. It represents the required visual quality. The image activity measure (IAM) is selected as an image feature. The relationship between IAM and image compression performance under different quantization parameters (QPs) is analyzed. Based on this relationship, proper QPs can be chosen for different images. Then JPEG XR can be used to compress images with these QPs, which will result in good visual quality with fewer bits consumed. The experiments have verified the effectiveness of the proposed method. How to choose a suitable image feature may be our future work.
