LEAD DirectShow Filters - Video De-Interlace Filter

Below are videos that demonstrate the DeInterlace filter.

What Causes Interlacing?

Some devices such as digital camcorders record 50 pictures (fields) per second, intermixing every 2 consecutive fields (with half the height) into 1 frame. Unfortunately, this can cause annoying lines especially with left to right movement. This annoyance can be removed by using the LEADTOOLS De-Interlace video filter.

Examples of Types of Applications

The De-Interlace filter would be extremely useful in any application that requires captures of full motion activities with digital video devices. A few examples are:

• Sporting events
• Scrolling marquees
• Traffic cameras

• Video Filters:
  
  Enhancements
  
• LEAD Video Add Filter† - Brightens a frame by adding two or more frames. Useful in correcting video taken in low-light conditions. For example, astronomers or video surveillance applications should find this filter useful.
  
  
• LEAD Auto Contrast Filter† -Changes the contrast without changing colors (hue). It makes the dark values darker and the light values lighter, which automatically enhances shadows and brightens the video stream.
  
  
• LEAD Auto Intensity Filter† - Performs color leveling on the RGB channel (the sum of the R, G, and B channels), without changing colors. It makes the dark values darker and the light values lighter, which automatically enhances shadows and brightens the video stream. It also maximizes the tonal range of the image and enhances the contrast and intensity using the image's histogram and a color distribution-based algorithm.
  
  
• LEAD Auto Level Filter† - Performs color leveling on the individual R, G and B channels, treating each of the R, G and B channels as a separate entity, without changing colors. It makes the dark values darker and the light values lighter, which automatically enhances shadows and brightens the video stream.
  
  
• LEAD Video Color Replace Filter† - Replaces any range of colors in a video stream with another range of colors.
  
  
• LEAD Video Color Filter† - Adjusts Hue, Saturation, Brightness, Contrast.
  
  
• LEAD Video Deblocking Filter† -Smoothes edges and removes the blocky artifacts present in highly compressed MJPEG or MPEG movies. Extremely useful for improving movies created by digital cameras that can take highly compressed, small video clips.
  
  
• LEAD Video Deinterlace Filter†† - Deinterlaces video with a pattern, deinterlaces only a region of interest (rectangle), and specifies segments in the video to deinterlace and how to deinterlace the segment (no deinterlace, interlace, deinterlace with pattern). There is also an “Auto Deinterlace” option which will check the video for interlacing and apply deinterlacing only if necessary.
  
  
• LEAD Video Resize Filter†† - Resizes the video by adjusting the width and height of the frames using normal resize, resample (bilinear interpolation), bicubic interpolation, or Bresenham interpolation.
  
  
• LEAD Video Crop Filter†† - Play, convert or capture only a specific rectangular area within the video.
  
  
• LEAD Video Rotation Filter†† - Flips, Reverses, Rotates 90, 180, and 270 degrees. Very useful when certain devices capture video in a rotated state.
  
  
• LEAD Video Unsharp Mask Filter†† - Powerful algorithm for edge enhancing. Improves the quality of some movies that look "washed out" because of resizing. The Video Unsharp Mask Filter produces better results than Video Edge Enhance.
  
  
• LEAD Video Edge Enhance Filter† - Improves the quality of some movies that look "washed out" because of resizing. The LEAD Video Edge Enhance Filter is similar to Video Unsharp Mask Filter, but much faster.
  
  
• LEAD Video Mosaic Filter† - Conceals a specific area in the video by making it blocky.
  
  
• LEAD Video Gamma Correction Filter† - Applies Gamma Correction (nonlinear brightness) to a video.
  
  
• LEAD Video Histogram Equalize Filter†† -Automatically increases the contrast and details in videos by using the histogram. This effect enhances videos that are too dark or too bright.
  
  
• LEAD Video Histogram View Filter†† - Draws the running histogram of a video stream in its property page. The filter also provides access to the histogram array through its programming interface. The histogram can be viewed for a single channel or for all channels.
  
  
• LEAD Video Text Overlay Filter†† - Adds static or moving text to videos with control over the font, font size, border and background. Additionally, an external XML file can be used to specify text to appear on specific frames.
  
  
• LEAD Video Overlay Filter†† - Superimpose a logo over a video.
  
  
• LEAD Video Callback Filter†† - Each video sample is provided in a callback for additional processing before being forwarded to the next component in the graph. The filter can be used during capture, playback or conversion.
