fill_interlacefill_interlacefill_interlaceFillInterlaceFillInterlace (Operator)

Name

fill_interlacefill_interlacefill_interlaceFillInterlaceFillInterlace — Interpolate 2 video half images.

Signature

Description

The operator fill_interlacefill_interlacefill_interlaceFillInterlaceFillInterlace calculates an interpolated full image or removes odd/even lines from a video image composed of two half images. If an image is recorded with a video camera it consists of two half images recorded at different times but stored in one image in the digital form. This can lead to several errors in further processing. In order to reduce these errors the video image is modified. Every second line is re-calculated or removed. The parameter ModeModeModeModemode determines whether this must be done for even ('even', 'rmeven') or odd ('odd', 'rmodd') line numbers. If you choose 'even' or 'odd' the gray values in the generated lines are calculated as mean values from the direct neighbors above or below the current pixel, respectively. If you choose 'rmeven' or 'rmodd' the even or odd lines numbers are removed (in that case the resulting image is only half as high as the input image). The value 'switch' for ModeModeModeModemode cause the odd and even lines to be exchanged.

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Automatically parallelized on tuple level.
• Automatically parallelized on channel level.
• Automatically parallelized on domain level.

Parameters

read_image(Image,'video_image')
fill_interlace(Image,New,'odd')
sobel_amp(New,Sobel,'sum_abs',3)

read_image(&Image,"video_image");
fill_interlace(Image,&New,"odd");
sobel_amp(New,&Sobel,"sum_abs",3);

read_image(Image,'video_image')
fill_interlace(Image,New,'odd')
sobel_amp(New,Sobel,'sum_abs',3)

read_image(Image,'video_image')
fill_interlace(Image,New,'odd')
sobel_amp(New,Sobel,'sum_abs',3)

read_image(Image,'video_image')
fill_interlace(Image,New,'odd')
sobel_amp(New,Sobel,'sum_abs',3)

Complexity

For each pixel: O(2).

Result

If the parameter values are correct the operator fill_interlacefill_interlacefill_interlaceFillInterlaceFillInterlace returns the value 2 (H_MSG_TRUE). The behavior in case of empty input (no input images available) is set via the operator set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). If necessary an exception is raised.
