Description

Image processing method and device

Technical field

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

Background technology

Fig. 1 is a kind of schematic diagram of the image procossing of SSAA in correlation technique.As shown in figure 1, in super sampling In antialiasing (SuperSampling Anti-Aliasing, referred to as SSAA), 16 circles are used to represent inside a pixel 16 sampled points, top dash area 1 and dash area 2 are the pixels covered.This is a kind of most intuitively at antialiasing Reason method, one big figure is rendered, has then reduced sampling (downsampl), it is equal equivalent to having done one inside each pixel 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).In the situation that hits is N Under, it is N that PS, which performs number, in each pixel, the N number of color of space-consuming (color)+N number of depth (depth).

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.MSAA is all in each pixel Exactly-once PS, output color write-in In the sampling sheet tested by depth template view (depth-stencil).Before Microsoft software Shader Model3, PS The certain center for being derived from pixel of input, added center (centric) interpolation later, PS input attribute can is triangle The center for all sampled points that shape is covered.As shown in Fig. 2 Fig. 2 is the image procossing of MSAA in correlation technique a kind of Schematic diagram.Wherein, circle is used to represent color samples (color sample), and cross is used to represent 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.If as shown in figure 1, not having center interpolation, two in dash area 1 sampled point will all Obtain the color of ethereal blue, the color of final pixel for (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).PS performs number each to cover the triangle of the pixel once in each pixel, the N number of color+N of space-consuming Individual depth.

Although MSAA solves the problems, such as calculating, but amount of storage is still very big, especially sample rate to more than 8.Cover Lid sampling antialiasing (CoverageSampling Anti-Aliasing, abbreviation CSAA) has decoupled color/depth buffering Device (buffer) and the buffer for covering (coverage), can be adopted with less color/depth spaces to store original height The getable quality of sample number.Such as situation as shown in Figure 1, 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 same color and Depth, as a result it 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).PS performs number each to cover the triangle of the pixel once in each pixel, space-consuming M color+M depth, M are less than N.

Deferred lighting technology (Deferred Lighting), which partly solves Deferred frameworks, 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 neighbours depth and normal (normal) difference degree Detection, each pixel can obtain a weight, for representing " as the degree at edge ", according to this weight, it is possible to need The buffer of anti-aliasing is, the color of neighbor pixel is brought into interpolation, obtains AA effect.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 correlation technique.

Fig. 4 is the schematic diagram according to a kind of MLAA of correlation technique image procossing.As shown in figure 4, form antialiasing (Morphological Antialiasing, referred to as MLAA) does not calculate isopleth (isoline), but divides door other edge Class, several specific shapes such as Z, U, L are summarized as, 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't neglect. On the one hand it is that they are surprising to the impact that memory space is brought.Especially on non-desktop platform, internal 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 original (primitive) sides to considering for " edge " Boundary, no matter whether this edge really needs AA, it can all waste many amounts of calculation.And MLAA amounts of calculation are huge, to hardware performance It is it is required that higher.

For above-mentioned image procossing amount it is big the problem of, not yet propose effective solution at present.
