In the present paper, Gabor wavelet bases properties are studied. A novel and effective method for Multi-orientation property of Gabor wavelet in astronomical image compression is introduced. A comparative analysis of orientation invariant feature extraction using different Gabor wavelet bases is discussed.
The main advantage of the Gabor wavelet transform are the multi-resolution analysis and multi-orientation property. Multi-orientation of Gabor bases function used to increase the resolution of compressed image in this paper, each orientation has level reflects characteristics of the image at a various directions and spatial resolution. Hence, it can analyze textures of image and detect edges of its with describe them at these orientations and resolutions. For this maters the Gabor wavelet transform concedered a best optimizations for image transformations.
Experimental results show that, whenever the angles increased for Gabor wavelets analysis, the astronomical compressed images have more accuracy and outperform better than the loss of angles orientation.
