Jpegpixi - JPEG Pixel Interpolator sounds like a pretty cool program for people with digital SLR cameras who are finding that "joy" of hot pixels and sensor dust.
‘Jpegpixi’ is short for ‘JPEG Pixel Interpolator’. The intent of the program is to interpolate pixels (single pixels, dots, stripes) in JPEG images. This is useful to correct images from a digital camera with CCD defects. For example, if one pixel is always bright green, this pixel can be interpolated with jpegpixi.
