Abstract
The embodiment of the invention discloses a method for realizing a special effect of oil painting of subtitles. By selecting and changing a gray value, RGB (Red, Green, Blue) values of all pixel points are corrected so as to achieve the special effect of oil painting; artistic effects of images and subtitles are enhanced; television artistic effects are enriched; and meanwhile calculation and storage resources are saved; the manufacturing efficiency is high; and the time and the resource are saved.
Description
Technical field
The present invention relates to fields such as captions, image processing, particularly a kind of method that realizes captions oil painting special efficacy.
Background technology
In existing program making and broadcast and correlative technology field, in the process to the program material making, in order better literal to be showed; Need a large amount of captions to synthesize, particularly in large-scale 3D film, material are made and play, in order to obtain better effect; Usually need in captions, insert the special efficacy effect, improve constantly, will carry out great amount of calculation by the GPU of graphic display card usually along with what special efficacy was required; In order to obtain the picture of high-quality; Therefore to the graphic operation processing speed, because calculating can relate to and call the GPU function and hardware is had higher requirement, the oil painting special efficacy of captions is exactly wherein a kind of.The oil painting special efficacy is meant and lets the captions image that perhaps font produces the variation effect of artistic oil painting.
In the prior art; Film titler in making, playing process, provide hardware and software environment preferably in oil painting captions special efficacy, and handles the restriction that the material processing speed receives the GPU disposal ability; And when playing, also there is a same requirement; In oil painting captions special efficacy building-up process, because handled a large amount of image files, so file needs bigger memory space and spatial cache.
Between above situation, in realizing process of the present invention, the inventor finds to exist at least in the prior art following problem:
Make in oil painting captions special efficacy, in the building-up process owing to need the jumbo memory space and the speed of service fast; So having relatively high expectations to graphic display card and GPU; In carrying out simple special efficacy building-up process, caused the waste of system, simultaneously; Also have many-sided restrictions such as the speed of service and disposal ability for playback equipment, the make one's cross making and the use of act special efficacy of oil supply brought restriction.
Summary of the invention
The invention provides a kind of method that realizes captions oil painting special efficacy, increased image, captions font artistic effect, enriched the video art effect, save computing and storage resources simultaneously, make efficiency is high, has practiced thrift time and resource.
Concrete grammar is following:
Select template radius parameter and smoothness parameter;
According to the template radius parameter search rectangle frame size is set and is (2M+1) * (2M+1), wherein the value of M is identical with the template radius parameter;
According to the smoothness parameter pixel grey scale interval 0～255 is divided into a N five equilibrium interval, wherein the value of N is identical with the smoothness parameter;
Set up the memory block of 2 two dimensions, with the rgb value of each pixel in the target captions according to pixels dot sequency read in first two-dimensional storage district;
According to the gray scale formula, calculate each gray values of pixel points, read in second two-dimensional storage district according to the pixel order;
Travel through all pixels, revise the rgb value of this pixel, the concrete grammar step is following:
In second two-dimensional storage district; With this pixel is the center; Judge which interval each pixel falls in the said search rectangle frame; Said which interval that falls into is meant which interval is this gray values of pixel points belong to, when a pixel falls into certain interval simultaneously, for this interval number statistical value adds 1;
Select the maximum interval of number statistical value, calculate the average gray of all pixels that fall into this interval, as this gray values of pixel points;
According to contrary gray scale formula, calculate the rgb value of this point, and replace the original rgb value of this pixel in first two-dimensional storage district with this rgb value;
With the each point rgb value that writes down in first two-dimensional storage district, play up the target captions again.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the embodiment of the invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below.
Fig. 1 is a kind of flow chart of realizing the method for captions oil painting special efficacy of the present invention.
Embodiment
To combine accompanying drawing below, the technical scheme in the embodiment of the invention will be carried out clear, intactly description.
The embodiment of the invention provides a kind of method that realizes captions oil painting special efficacy, and is as shown in Figure 1, and the practical implementation step is following:
Select template radius parameter and smoothness parameter;
According to the template radius parameter search rectangle frame size is set and is (2M+1) * (2M+1), wherein the value of M is identical with the template radius parameter;
According to the smoothness parameter pixel grey scale interval 0～255 is divided into a N five equilibrium interval, wherein the value of N is identical with the smoothness parameter;
Set up the memory block of 2 two dimensions, with the rgb value of each pixel in the target captions according to pixels dot sequency read in first two-dimensional storage district;
According to the gray scale formula, calculate each gray values of pixel points, read in second two-dimensional storage district according to the pixel order;
Travel through all pixels, revise the rgb value of this pixel, the concrete grammar step is following:
In second two-dimensional storage district; With this pixel is the center; Judge which interval each pixel falls in the said search rectangle frame; Said which interval that falls into is meant which interval is this gray values of pixel points belong to, when a pixel falls into certain interval simultaneously, for this interval number statistical value adds 1;
Select the maximum interval of number statistical value, calculate the average gray of all pixels that fall into this interval, as this gray values of pixel points;
According to contrary gray scale formula, calculate the rgb value of this point, and replace the original rgb value of this pixel in first two-dimensional storage district with this rgb value;
With the each point rgb value that writes down in first two-dimensional storage district, play up the target captions again.
The present invention includes but be not limited to the embodiment of above description, any those skilled in the art need not pay that creative work just can think of variation all should fall into protection scope of the present invention.
