We investigated different Image Processing algorithms using sequential and cuda parallel programming. Landsat8 images of Houston, Texas are subjected as input for various image processing algorithms. IHS, Brovey and Gram Schmidt algorithms are developed in C and Cuda languages. Red Green, Blue and panchromatic images are input for these algorithms. Panchromatic image is a single band image generally displays as a shades of Gray. After processing, these algorithms produces color image with higher resolution.Execution time for Brovey and Gram Schmidt are improved when using cuda parallel programming. Various Data Sets are subjected as input for these algorithms.Execution time for different data sets using C and Cuda programming are recorded.
