名称

fill_interlacefill_interlaceFillInterlaceFillInterlacefill_interlace — Interpolate 2 video half images.

参数签名

描述

该算子 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.

For an explanation of the concept of smoothing filters see the introduction of chapter Filters / Smoothing.

注意

Note that filter operators may return unexpected results if an image with a reduced domain is used as input. Please refer to the chapter 过滤器.

Complexity

For each pixel: O(2).

结果

If the parameter values are correct 该算子 fill_interlacefill_interlaceFillInterlaceFillInterlaceFillInterlacefill_interlace 返回值 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>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>). If necessary an exception is raised.
