描述

算子 fill_interlacefill_interlaceFillInterlaceFillInterlaceFillInterlacefill_interlace 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 ModeModeModeModemodemode determines whether this must be done for even ('even'"even""even""even""even""even", 'rmeven'"rmeven""rmeven""rmeven""rmeven""rmeven") or odd ('odd'"odd""odd""odd""odd""odd", 'rmodd'"rmodd""rmodd""rmodd""rmodd""rmodd") line numbers. If you choose 'even'"even""even""even""even""even" or 'odd'"odd""odd""odd""odd""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'"rmeven""rmeven""rmeven""rmeven""rmeven" or 'rmodd'"rmodd""rmodd""rmodd""rmodd""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'"switch""switch""switch""switch""switch" for ModeModeModeModemodemode cause the odd and even lines to be exchanged.

注意

请注意，若使用域缩减后的图像作为输入，滤波器算子可能会返回意外结果。请参阅 滤波器 一章

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 在元组级别上自动并行化。
• 在通道级别上自动并行化。
• 在域级别上自动并行化。

参数

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)

复杂度

For each pixel: O(2).

结果

如果参数值正确，算子 fill_interlacefill_interlaceFillInterlaceFillInterlaceFillInterlacefill_interlace 返回值 2 ( H_MSG_TRUE )。当输入为空（无可用输入图像）时可设置行为通过算子 set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>)。如有必要，则抛出异常。
