Re: Adobe takes the Public to be Mindless Chumps

Adobe Corporation:

"UPDATE: For those who are curious – some additional background on the images used during the recent MAX demo of our “deblur” technology. The first two images we showed – the crowd scene and the image of the poster, were examples of motion blur from camera shake."

The image that appears in the left-half of your now widely disseminated "plaza.png" (allegedly "motion-blurred" as a result of "camera shake" has a mean (average) value (in the vertical as well as the horizontal dimensional axes) that appears to be equal to the allegedly "clarified" image that appears in the right-half of your now widely disseminated "plaza.png".

Had the image that appears in the left-half of "plaza.png" actually been generated by a real-world camera in (angular or linear, in the vertical or horizontal axes) motion, such a result would (for all practical purposes) be essentially impossible (or so improbable as to be highly suspect, to say the least).

Determining (and thus verifying) my assertion can be very easily done - using a copy of Adobe's now widely disseminated "plaza.png" image, and the software applications Photoshop (or even more easily, it appears, using PaintShop Pro).

The procedure is relatively simple, and need not be absolutely precise:

(1) As the two halves of the "plaza.png" image are (curiously) not precisely aligned, it is necessary to crop a similar section from each half which includes image-detail. This is relatively easy to do. I did it manually three separate times, with success in each of those three separate efforts.

(2) It is recommended that each of the two (blurred and un-blurred) crops then be converted from color to gray-scale (to facilitate the viewing process).

(3) Then, using Photoshop, PaintShop Pro, or any other image-processing application capable of performing image-averaging [ ( A + B ) / ( 2 ) ], combine the crops derived from the left and the right halves of "plaza.png" (with equal weighting) while also scaling the combined images by a factor of one-half (in order to ensure that the result remains with the maximum gray-level value).

You will surely be astounded and quite amazed to find that the (so averaged) result is extremely "sharp" and well-defined, and that a very high level of fine-details can readily be seen in the resulting averaged image (including even the smallest signage-lettering existing in the far-field of the image).

Again: had the image that appears in the left-half of "plaza.png" actually been generated by a real-world camera in (angular or linear, in the vertical or horizontal axes) motion, such a result would (for all practical purposes) be essentially impossible (or so improbable as to be highly suspect, to say the least).

For those readers who do not own a copy of PaintShop Pro (which performs such image-averaging in a one-click arithmetic operation in the "Arithmetic" tools), you will find instructions for relatively [easily] accomplishing such image-averaging of two images using layers in Photoshop. See the "Averaging Images in Photoshop Using Layers" section here:

Thank you, Adobe, for making it so trivial for any interested party to very easily determine that the image appearing in the left-half of "plaza.png" could not possibly have been generated by an actual camera in motion - and I (and a few others, I imagine, at this point) look forward to reading Adobe's forthcoming statement which comes forth with the actual and unvarnished truth surrounding what (rather rudimentary, and with a zero-mean) synthetic methods have (also, in the case of "plaza.png") been used to mock this one up, as well.
