Description

Image processing method and device

Technical field

The present invention relates to image processing fields, in particular to a kind of image processing method and device.

Background technology

Fig. 1 is the schematic diagram according to the image procossing of SSAA in the related technology a kind of.As shown in Figure 1, in super sampling In antialiasing (SuperSampling Anti-Aliasing, referred to as SSAA), 16 circles are for indicating inside a pixel 16 sampled points, top dash area 1 and dash area 2 are the pixels covered.This is at a kind of most intuitive antialiasing Reason method has rendered one big figure, has then reduced sampling (downsampl), has been equivalent to inside each pixel and done one Even profile samples.

Each sampled point is carried out one time, can obtain 1 white sampled point (1,1,1), 1 light blue sampled point (0.77,0.77,1) and 14 yellow sampled points (1,1,0).The value of this last pixel is being averaged for this 16 sampled points, That is, ((1,1,1)+(0.77,0.77,1)+14* (1,1,0))/16=(0.98,0.98,0.125).The case where hits is N Under, it is N, the N number of color of occupied space (color)+N number of depth (depth) that PS, which executes number, in each pixel.

SSAA needs to be carried out an image procossing (PS), and save colors (color) and depth in each sampled point (depth), time and space expense are all surprising.Multiple sampling antialiasing (MultiSampling Anti-Aliasing, Referred to as MSAA) appearance significantly improve this point.For MSAA in each pixel Exactly-once PS, output color write-in is all In the sampling sheet tested by depth template view (depth-stencil).Before Microsoft software Shader Model3, PS Input be centainly derived from the center of pixel, added center (centric) interpolation later, the input attribute of PS can be triangle The center for all sampled points that shape is covered.As shown in Fig. 2, Fig. 2 is the image procossing according to a kind of MSAA in the related technology Schematic diagram.Wherein, circle is for indicating color samples (color sample), and cross is for indicating depth-sampling (depth sample).Left figure in Fig. 2 is the schematic diagram without the image procossing using central difference, and the right figure in Fig. 2 is using center The schematic diagram of the image procossing of difference.As shown in Figure 1, if not having center interpolation, two sampled points in dash area 1 will all Obtain the color of ethereal blue, the color of final pixel be (2* (0,0,1)+14* (1,1,0))/16=(0.875,0.875, 0.125).It is exactly more accurate light blue ((1,1,1)+(0.77,0.77,1))/2=if having centric interpolation (0.885,0.885,1), final pixel color be (2* (0.885,0.885,1)+14* (1,1,0))/16=(0.98,0.98, 0.125).In each pixel PS execute number be each cover the pixel triangle it is primary, the N number of color+N of occupied space A depth.

Although MSAA solves the problems, such as calculating, but amount of storage is still very big, especially sample rate to 8 or more.It covers Lid sampling antialiasing (CoverageSampling Anti-Aliasing, abbreviation CSAA) has decoupled the buffering of color/depth Device (buffer) and the buffer for covering (coverage), can be adopted with the less spaces color/depth to store original height The getable quality of sample number.For example, situation as shown in Figure 1, is rendered with CSAA 16x, a pixel will be divided into a left side There are 4 coverage sampled points in upper, upper right, lower-left and 4 pieces of bottom right region, every piece of region, but share the same color and As a result depth is exactly (0.25* (0.885,0.885,1)+0.25* (0.885,0.885,1)+3.75* (1,1,0))/4= (0.98,0.98,0.125).In each pixel PS execute number be each cover the pixel triangle it is primary, occupied space M color+M depth, M are less than N.

Deferred lighting technology (Deferred Lighting), which partly solves Deferred frames, can not use hardware MSAA The problem of, but the cost of one side scene or no small is rendered again.

Edge antialiasing (Edge AA) is to do an edge according to the difference degree of neighbours depth and normal (normal) Detection, each pixel can obtain a weight, for indicating " as the degree at edge ", according to this weight, so that it may to need The color of neighbor pixel is brought interpolation, obtains the effect of AA by the buffer for doing anti-aliasing.As shown in Figure 3.Wherein, Fig. 3 is root According to a kind of schematic diagram of the treatment effect of edge antialiasing of the relevant technologies.

Fig. 4 is the schematic diagram according to the image procossing of MLAA of the relevant technologies a kind of.As shown in figure 4, form antialiasing (Morphological Antialiasing, referred to as MLAA) does not calculate isopleth (isoline), but divides door other edge Class is summarized as several specific shapes such as Z, U, L, and Z and U can be decomposed into L.

These methods of above-mentioned SSAA, MSAA, CSAA need hardware directly to support, but the overhead brought can not be underestimated. It is surprising to the impact that memory space is brought that one side, which is them,.Especially on non-desktop platform, memory is natively few, such as Fruit also needs to just less qualified to do it if AA.On the other hand, these methods are all the original sides (primitive) to considering for " edge " Boundary can all waste many calculation amounts no matter whether this edge really needs AA.And MLAA calculation amounts are huge, to hardware performance It is required that higher.

For the big problem of above-mentioned image procossing amount, currently no effective solution has been proposed.
