  2. Display Stream Compression - Wikipedia

    en.wikipedia.org/wiki/Display_Stream_Compression

    Display Stream Compression (DSC) is a VESA-developed video compression algorithm designed to enable increased display resolutions and frame rates over existing physical interfaces, and make devices smaller and lighter, with longer battery life. [1]

  3. Test card - Wikipedia

    en.wikipedia.org/wiki/Test_card

    Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.

  4. Video quality - Wikipedia

    en.wikipedia.org/wiki/Video_quality

    Video quality is a characteristic of a video passed through a video transmission or processing system that describes perceived video degradation (typically compared to the original video). Video processing systems may introduce some amount of distortion or artifacts in the video signal that negatively impact the user's perception of the system.

  5. Comparison of video codecs - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_video_codecs

    The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.

  6. Standard test image - Wikipedia

    en.wikipedia.org/wiki/Standard_test_image

    A standard test image is a digital image file used across different institutions to test image processing and image compression algorithms. By using the same standard test images, different labs are able to compare results, both visually and quantitatively. The images are in many cases chosen to represent natural or typical images that a class ...

  7. Image quality - Wikipedia

    en.wikipedia.org/wiki/Image_quality

    Image quality can be assessed using objective or subjective methods. In the objective method, image quality assessments are performed by different algorithms that analyze the distortions and degradations introduced in an image. Subjective image quality assessments are a method based on the way in which humans experience or perceive image quality.

  9. Structural similarity index measure - Wikipedia

    en.wikipedia.org/wiki/Structural_similarity...

    The window can be displaced pixel-by-pixel on the image to create an SSIM quality map of the image. In the case of video quality assessment, [ 6 ] the authors propose to use only a subgroup of the possible windows to reduce the complexity of the calculation.
