Change Image Size With AKVIS Magnifier AI: Old Algorithm

AKVIS Magnifier AI: Old Algorithm

AKVIS Magnifier AI lets you change the size of an image without loss in quality. The software allows enlarging an image to a super-high resolution of up to 30,000 x 30,000 pixels (300,000 in the 64 bit version).

The parameters are grouped in sections: Downsize and Upsize. Depending on the New Size value, different parameters will be active.
By using the hot-key combination Alt+underlined letter you can quickly move the focus into the corresponding entry field.

To avoid distortion of details, it is recommended to scale the image to its original size (100%) before changing the settings of the program.

 

Downsize (reducing an image):

Sharpness (0-100). The parameter increases image sharpness by intensifying the color contrast between the neighboring pixels. The higher the value of the parameter, the sharper the image becomes.

Reducing an image: weak sharpness
Sharpness = 20
Reducing an image: increased sharpness
Sharpness = 80

Remove Noise (0-25). The parameter lets removing noise and defects by increasing the level of smoothness. The higher the value, the smoother the result is.

Without Smoothness
Remove Noise = 0
Noise Removal
Remove Noise = 10

 

Upsize (increasing an image):

Sharpen Edges (0-100). This parameter increases the sharpness and intensity of the object's edges.

Resized image
Sharpen Edges = 0
Change "Sharpen Edges"
Sharpen Edges = 80

Edge Smoothness (1-8). This parameter smoothes color gradients on the border of contrasting color zones. At high values of the parameters the border looks softer. At low values of the parameter the border line looks uneven and irregular: it is very visible on an image with contrasting color zones.

Reduce "Edge Smoothness"
Edge Smoothness = 1
Increase "Edge Smoothness"
Edge Smoothness = 8

Simplicity (0-400). This parameter sets the level of detail on the final image. The higher the value of the parameter, the more simplified and artificial the result will look; the lower the value, the more details will be visible. The sharpness/smoothness of the image is influenced at the same time by the size and the scale of the image. At high values of the Sharpen Edges parameter, the difference between the original and the simplified image increases.

Reduce "Simplicity"
Simplicity = 10
Increase "Simplicity"
Simplicity = 380

Grain (0-25). This parameter adds slight noise to the image. It is helpful in case of an oversmoothed image (an image processed with high values of the Sharpen Edges parameter and a high level of Simplicity).

Resized image
Grain = 0
Sharpen Edges = 50, Simplicity = 300
Add "Grain"
Grain = 15
Sharpen Edges = 50, Simplicity = 300

Remove Artifacts (0-100). The parameter lets removing defects that appear when resizing images. It smooths the pixelated image while preserving the edges and details.

Remove Artifacts = 0
Remove Artifacts = 0
Remove Artifacts = 60
Remove Artifacts = 60

Also, you can smoothen the image with the Remove Noise parameter which is available in both groups: Upsize and Downsize (see its description above).

Unsharp Mask. This tool sharpens the image by increasing contrast between the pixels. When the check-box is enabled, the program compares the resulting image with its blurred copy and if the pixel of the image contrasts with the pixel of the blurred copy, the contrast is increased; otherwise, the pixel stays unchanged. The program processes all image pixels in this way.
