ImageMagick's convert: no images defined
You can try specifying the filename after the composite operator, something like this:
$ convert 1.png \ -filter 'Jinc ( +clone -negate -morphology Distance Euclidean -level 50%,-50% )' \ -morphology Distance Euclidean \ -compose Plus \ -composite 1.png \ -level 43%,57% \ -resize 12.5% 1.png
