Super resolution (SR) images play an important role in Image processing applications.Spatial resolution is the key parameter in many applications of image processing.Super resolution images can be used to improve the spatial resolution.In this paper a new SR image reconstruction algorithm is proposed using Integer wavelet transform (IWT) and Binary plane technique (BPT).The proposed method is analyzed in different color space transforms such as CIELAB, YC b C r and RGB.In this paper we compared PSNR, ISNR, Blocking effect and Homogeneity with different colour images in RGB, YC b C r and CIELAB domains.Qualitative analysis shows that the proposed method in CIELAB color space transforms has better performance.
