The filter for Adobe Premiere to remove video noise on VHS movie. Its main task is suppression of noise as small bright lines, red or blue color, less often green. Because of discontinuity of a magnetic layer of VHS-tape such lines always are present at the image.
The filter analyses each frame irrespective of others, due to what it brings in additional distortions in comparison with dynamic filters (practically there is a loss of clearness in comparison with the operation blur). In aggregate with high accuracy of definition of noise the given filter, probably, is the leader among similar filters for VirtualDub. Is especially convenient at coding in MPEG4 or DivX, since even after deleting small noise the size of the encoded file decreases.
The level cut of noise can be regulated for any of color components. The filter is optimized for processors with support MMX-technology.

AKVIS Noise Buster is software for noise suppression on digital and scanned images.
Digital cameras opened the door to easy and entertaining photography. However, consumer digital cameras also have their drawbacks: they often produce the so-called digital noise. It can be seen as grains that compromise the smoothness of the photo. It is especially annoying on the skin as it makes it uneven. This kind of noise is called luminance noise. There can also be chroma (color) noise which is perceived as random red and blue pixels spoiling the color accuracy of the snap-shot.
Digital noise can be produced by a number of factors: heating of the camera sensor, long exposure shooting, small pixel size (therefore digital compact cameras generate much noisier images than digital SLRs), high ISO settings, etc.
AKVIS Noise Buster reduces both luminance and color noise on digital images without spoiling other aspects of the photo. Now your photos look neat and accomplished.
There is an option of automatic filtering based on the analysis of the overall image noise. If not quite satisfied, you can tweak the parameters observing the changes in real time in the preview window.
The program's window shows Before and After images for instant preview and easy tweaking of the parameters. You can switch between the windows with a click on the image. Separate setting areas for luminance and chroma noise allow you to deal with each kind of noise in the most efficient way. For further adjustment you have a few advanced parameters at your disposal.
The histogram displaying the noise level and noise components of the loaded image will help you to adjust settings.
AKVIS Noise Buster is available in two editions: as an independent application (standalone) and as a plug-in to a photo editor: Adobe Photoshop, Photoshop Elements, Corel (Jasc) Paint Shop pro, etc.
The plugin supports Batch Processing that allows applying the same settings to a folder full of images.

UnJPEG is a professional, effective and user-friendly application, specially designed to help graphic designer's studios/publishing houses to recover images damaged by JPEG compression. If you are familiar with the consequences of JPEG compression, you will certainly appreciate this powerful and versatile tool. JPEG is the default format used by graphic editors, as well as the format for many digital cameras to save their images. JPEG compression does not save all of the information contained in an image so, when not set to a 100% quality in order to save disk space, it damages the quality of the image by disturbing its size and giving it a slightly dithered effect. UnJPEG is a perfect solution to achieve your final goal – better quality. This software is a professional tool, which recovers JPEG images, removes the so-called 'JPEG artifacts' and improves image clarity. The product features two different types of compression-artifact detection and analysis (file and heuristic based), JPEG-artifact removal, median-noise reduction, smooth image resizing, recovering images damaged by JPEG compression, blotchy look removal, contrast increase and crispness control, as well as returning to defaults at any time. Moreover, this software gives clarity and a real-life effect to pictures taken with digital cameras. UnJPEG supports Microsoft Windows 95, 98, 2000, Me, XP or NT 4.0. Great value for a reasonable price, UnJPEG is a perfect investment, and works effectively, efficiently and smartly.

PhotoAcute Studio improves the quality of photographs taken with digital cameras and camera phones. It increases resolution, reduces noise, removes chromatic aberrations, corrects brightness of overexposed and underexposed parts of the picture.

Most modern digital cameras and some camera phones support the so-called "continuous shooting" or "burst" mode. PhotoAcute Studio is an application primarily developed for processing sets of digital photographs taken in "continuous mode" to produce high-resolution, low-noise pictures. You will get amazing image quality improvement without changing your camera.

PhotoAcute Studio main features:

* Larger picture with super-resolution - more pixels in the image. By applying state-of-the-art super-resolution algorithms, tuned to a particular camera, PhotoAcute Studio produces up to 4 times larger photographs. That is not the digital zoom - the photographs really have more pixels, thus giving you more details. Small, thin and far away objects, traceries, textures and inscriptions become recognizable.

* Strong noise reduction without loosing the details. By correlating several snapshots, PhotoAcute Studio automatically reduces the noise on the photographs, without losing useful graphical information.

* The details in underexposed and overexposed parts of an image become visible.

* Color fringing correction. Every lens focuses light with different wavelengths on different positions. This causes chromatic aberration that is seen as "fringes" of color around the image. PhotoAcute corrects this aberration, minimizing the circle of confusion.

* Removal of unneeded moving objects from the scene.

* Fixing handshaking artifacts in low light conditions.

Our time-unlimited free trial mode allows you to evaluate all image processing features.

Enlarge images to high resolution with sophisticated algorithms. AKVIS Magnifier upscales digital images with advanced enlargement algorithms, preserving edge to edge image sharpness while improving image appearance by removing unwanted noise and compression artifacts. Get super-high resolution pictures and produce stunning enlargements and poster-size prints. The sophisticated algorithms keep edges smooth, sharp and clearly defined at the same time.

AKVIS Magnifier makes producing professional enlargements and poster-size prints easy and quick. Available for Windows and Mac, AKVIS Magnifier does not require an external photo editor to operate. The resizing is easily configurable and allows fine-tuning the enlargements by introducing complete user control over important parameters such as image and edge sharpness. All settings can be quickly tried, adjusted and combined by simply clicking and sliding.

Just take a photo and enlarge it to a super-high resolution of up to 30000x30000 pixels, to print a100x100 inch poster with typographic quality of 300dpi. Larger formats are viewed from the distance, allowing for even larger prints of 200x200 inches a whooping 5x5 meters.

Resizing pictures with AKVIS Magnifier yields a much higher quality than bicubic interpolation. Using complex math based on sophisticated resize algorithms, the resizer outputs enlargements with smooth, sharp and clearly defined edges. Depending on your particular needs, AKVIS Magnifier can be fine-tuned to produce images that look exactly as required for a given purpose. The photo enlarger works great if a modest 1.1x, 2x or 4x enlargement is needed, but it truly shines if used to blow up a photo to 10x or 20x the original size.

Whether creating poster-size images or adding resolution for printing an enlargement, AKVIS Magnifier will make your prints look sharper, clearer and better defined.
