A New Hybrid Wavelet Based Approach for Image Fusion

Gagandeep kaur , Anand Kumar Mittal

With the availability of multi-sensor data in many fields, image fusion has been receiving increasing attention in the researches for a wide spectrum of applications. Image fusion is the process that combines information from multiple images of the same scene. These images may be captured from different sensors, acquired at different times, or having different spatial and spectral characteristics. Discrete wavelet transform (DWT) was performed on source image. Because DWT is the basic and simplest transform among numerous multi-scale transform and other type of wavelet based fusion schemes are usually similar to the DWT fusion scheme. In this paper, hybrid method for image fusion is proposed. The method used is combination of DCT (Discrete Cosine Transform) and Variance and compared it with Hybrid DWT.
