Public bug reported: Enfuse results in a brightness mismatch of dark deghosted areas when exposure-mu is decreased from its default value.
Program Version: - enfuse 4.1.3 (could not compile 4.2) Platforms: - Debian Jessie - OS X 10.11.6 via MacPorts == Testcase Files == https://www.dropbox.com/sh/8la13xukmfamjk5/AACI6mruatMEsZ27wZgl8ysha?dl=0 Bracketed exposures: 161022_tc2_7079.tif - RGBA 161022_tc2_7081.tif - RGBA 161022_tc2_7083.tif - RGBA 161022_tc2_7085.tif - RGBA 161022_tc2_7086.tif - RGB Enfused results: 161022_mu00.tif - exposure-mu=0.0 161022_mu02.tif - exposure-mu=0.2 161022_mu05.tif - exposure-mu=0.5 (default) Commands to reproduce: $ enfuse --exposure-mu=0.0 -o 161022_mu00.tif 161022_tc2_70??.tif $ enfuse --exposure-mu=0.2 -o 161022_mu02.tif 161022_tc2_70??.tif $ enfuse --exposure-mu=0.5 -o 161022_mu05.tif 161022_tc2_70??.tif == Detailed Description == Deghosting; All exposures except the lightest one (..7086) share the same alpha channel which masks a dark area in the middle of the image for deghosting of moving leaves. The masking is binary, there are no partially masked pixels. When I change the exposure-mu parameter from its default 0.5 to a smaller value to darken the image, the deghosted area stays much lighter than its surroundings. The problem does not occur when deghosting a bright area using pixels from a dark exposure. ** Affects: enblend Importance: Undecided Status: New -- You received this bug notification because you are a member of Hugin Developers, which is subscribed to Enblend. https://bugs.launchpad.net/bugs/1649122 Title: Enfuse brightness mismatch in deghosted area Status in Enblend: New Bug description: Enfuse results in a brightness mismatch of dark deghosted areas when exposure-mu is decreased from its default value.
