Abstract
Bused on theory of wavelet transform, images are analyzed. On this basis, image enhancement is analyzed to apply with wavelet transform. Results are analyzed and compared with low-pass filtering and high-pass filtering of frequency domain method and linear filtering and non-linear filtering of space domain method, indicating better to improve the image to adopt wavelet transform.
