Real Time Image Fusion using Multi Resolution Discrete Sine Transform

Image fusion is a process, used to fuse two or more images into one image without any loss of data, images are taken from different sensors in different Field Of View (FOV). In recent days, image fusion is playing an important role in research areas. In open literature different fusion techniques are available like Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) etc., this paper is aimed at the design and development of image fusion using MDST for still images and for real-time images. Multi-resolution DST (MDST) has been developed for multi imaging sensor data fusion. This fusion algorithm has been evaluated using both still images as well as real-time images. IR and EO cameras were connected to multi-functional display system through frame grabber. MDST algorithm has been ported (Visual C++) and tested on10.4” multi function display. The MDST results are comparable with DWT (Discrete Wavelet Transform). The proposed fusion algorithm can be used in battlefields, remote sensing applications and medical imaging etc.
