摘要：
This paper proposes two image enhancement algorithms that are based on utilizing histogram data gathered from wavelet transform domain coefficients. Computer simulations demonstrate that combining the spatial method of histogram equalization with the logarithmic transform domain coefficient histograms achieves a much more balanced enhancement, which outperforms classical histogram equalization algorithms.
