EXPENSIVE SOFTWARE CANNOT ENLARGE PHOTOS
As we wrote in our photo enlargement and interpolation newsletter (click here)
and as we've been writing about for years now, even expensive
software like Paint Shop Pro® and Photoshop® still
cannot enlarge photos nearly as well as even Imagener Enhanced
because they have not improved the part of the program that
enlarges images (called an algorithm) for years. Photoshop® and
Paint Shop Pro® do many other things extremely well,
and they have dozens of functions that the Imagener product
line does not have, but when it comes to photo enlargement,
nothing compares to Imagener.
Don't believe it? See the image below. It has been reduced
in resolution and size for this example, but we used its larger
parent image to demonstrate. We are going to isolate the gumball
machine and enlarge it in Photoshop and Imagener
show you the difference.
Small Version of Original Image |
Imagener Enhanced and Professional perform the information calculation and
storing operations without the vectorization process, and both provide
much better visual results than Photoshop® or Paint Shop Pro® possibly
|We sliced out a piece of the gumball
machine for this demonstration. The image to the right was enlarged
using Photoshop® with its bicubic interpolation algorithm.
Notice how it fell apart. Bicubic interpolation analyzes the 16
pixels around each individual pixel and uses that information for
the new pixel
The weighted average of the closest 16 pixels (a 4x4 matrix) is
calculated based on small distances. Using this method, enlargements
above 120% to 150% quickly degrade in quality and visual clarity.
|All of the enlargement methods in Imagener
Unlimited are significantly better than this method because
the Imagener enlargement engines are much more intelligent. For
example, Imagener Unlimited first analyzes
the complexity of the entire photo for enlargement purposes. The image to the
right is a graphical depiction of this analysis. Complexity is
mapped according to image objects, colors and similarities and
differences of large regions together, not just the surrounding
16 pixels of each pixel. This information is stored in memory
in preparation for the next stage, vectorization of the image.
Unlimited then computes what is called a "vector map" down
to the single pixel level. In the first stage it has stored all
of the information that bicubic interpolation provides, plus
three additional arrays of data that describe complexity, color
and similarities or differences between regions. Using that information,
the vector map is calculated. The image to the right is a visual
representation of this vector map - a process that the user does
not see as it is performed during the enlargement process across
the entire photo before the actual enlargement takes place.
|After the Imagener
Unlimited converts the image to vector
to a virtually unlimited scale is then possible because four levels of image
information have been calculated and stored - then vectorized.
Once the image is in this format, blowing the image up to huge
proportions while maintaining image clarity and integrity is
possible. The bicubic method used by Photoshop® and Paint
Shop Pro® just pull pixels apart into blocks because the
enlargement process has no image information stored in memory
and the image is not in a form that allows it to stay intact
visually. Finally, Imagener
Unlimited converts the enlarged result back to its original
