Multi-focus Image Fusion Using an Effective Discrete Wavelet Transform Based Algorithm

Abstract: In this paper, by considering the main objective of multi-focus image fusion and the physical meaning of wavelet coefficients, a discrete wavelet transform (DWT) based fusion technique with a novel coefficients selection algorithm is presented. After the source images are decomposed by DWT, two different window-based fusion rules are separately employed to combine the low frequency and high frequency coefficients. In the method, the coefficients in the low frequency domain with maximum sharpness focus measure … Show more

“…En algunos otros trabajos se propone tratar el problema como un proceso de optimización para el cálculo de los pesos que se asocian a cada píxel de las imágenes Garnica, 2014) y (Calderon et al, 2016). En otros trabajos se propone usar la transformada Wavelet para determinar las regiones de cada imagen que deben conformar la imagen final (Li et al, 1995;Zhang and Blum, 1999;Pajares and de la Cruz, 2004;Shi et al, 2005;Li and Yang, 2008a;Malviya and Bhirud, 2009;Li et al, 2010;Tian and Chen, 2010;Yang, 2011;Shah et al, 2013;Yang et al, 2014).…”

“…Yang et al en (Yang et al, 2014) realizan el cálculo del mapa de decisión usando transformada Wavelet y calculando la energía en una vecindad con un kernel de Sobel. Zhou et al en (Zhou et al, 2014), también proponen el cálculo del mapa de decisión usando la información del gradiente a diferentes escalas.…”

“…There are four indices used for comparison of IQA measures [38], [39]: Spearman Rank order Correlation Coefficient (SRCC), Kendall Rank order Correlation Coefficient (KRCC), Pearson linear Correlation Coefficient (PCC), and Root Mean Square Error (RMSE). It is worth noticing that RMSE is widely used in the development of image processing algorithms, e.g., in [40]. SRCC and KRCC evaluate prediction monotonicity, while PCC and RMSE evaluate prediction accuracy.…”
