Figure 1From: Fast target detection method for high-resolution SAR images based on variance weighted information entropyThe WIE value of a real SAR image in different areas. (a) The original image. (b) A uniform area, WIE = 0.58. (c) An area including the ups and downs, WIE = 0.76. (d) An area which contains the target, WIE = 0.82. The sizes of (b,c,d) are all 100 × 100 pixels.Back to article page
