Most cameras in orbit eventually get bad/hot/cold pixels due to radiation damage. As that is a sensor defect, the same pixel will always be affected so averaging won't eliminate this issue. Sort of a unique side effect from being in space.Jameshttps://www.blogger.com/profile/17920571694195348575noreply@blogger.comtag:blogger.com,1999:blog-7070350096643865407.post-59084337084944931292018-05-31T08:36:23.600-07:002018-05-31T08:36:23.600-07:00I think It is important to note that what you are ...I think It is important to note that what you are speaking of here is NOT Image "Stacking". What you are presenting here is called Frame Integration / Frame Averaging. This is different from stacking because frame integration does NOT attempt to shift the images based upon the objects in the scene prior to averaging the pixels POST alignment.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7070350096643865407.post-73280017903686265172018-05-04T01:03:34.004-07:002018-05-04T01:03:34.004-07:00Hi i am also facing the above mentioned error. my ...Hi i am also facing the above mentioned error. my file type is pngAradhyahttps://www.blogger.com/profile/06377203446016426771noreply@blogger.comtag:blogger.com,1999:blog-7070350096643865407.post-45889612774066382132015-10-12T16:41:24.279-07:002015-10-12T16:41:24.279-07:00What file-type are you trying to read? png, jpg?What file-type are you trying to read? png, jpg?onlyjushttps://www.blogger.com/profile/14236929826206309645noreply@blogger.comtag:blogger.com,1999:blog-7070350096643865407.post-28323538097549440072015-10-12T14:39:32.360-07:002015-10-12T14:39:32.360-07:00Hi,
