The present disclosure provides an image processing method and apparatus. The method comprises: obtaining an RGB image and a stencil buffer, wherein the RGB image comprises image information taken by a physical camera and image information rendered by a virtual object rendering module, and the stencil buffer is used for storing stencil values corresponding to pixels on the RGB image; obtaining a target image by processing the RGB image according to the stencil buffer; obtaining a post-processed image by post-processing the target image; determining an image to be displayed according to the post-processed image. In this way, the post-processing object is flexible and controllable. The user therefore has a stronger sense of participation and a better experience.

The present application relates to virtual reality image processing technical field, disclose a kind of virtual reality ideological and political content adaptive generation method based on affective computing, comprising: user physiological signal is mapped as visual intervention weight coefficient;Preload reference and target color lookup table;In rasterization stage, the mask identification of information primitive is written to template buffer;In fragment shading stage, read template value, if matching mask identification, then weight is zero, otherwise keep weight;Based on weight, linear interpolation is performed on the sampling value of double lookup table, the present application realizes global atmosphere rendering and local information fidelity pixel-level decoupling by template buffer, solves the problem that key information is lost due to dynamic visual style reconstruction under constant computing power overhead.

If the complete image is synthesized, important information for image generation, such as video generation for computer games, may be lost. To avoid this, a customized capture script (600) is created for a computer game that specifies (502) what to capture for future use (504) from the frame buffer (400), depth buffer (402), stencil buffer (404), etc., during the rendering of a game video frame. The script also specifies when data should be recorded during frame rendering. By capturing data mid-frame, on-screen object boundaries and relative distances between objects can be inferred. This information can be used (506) for 2D to 3D conversion, object coloring for increased contrast, object highlighting, etc.

In various examples, systems and methods are disclosed relating to quantifying the overlaps among a plurality of two-dimensional shapes. A system can identify a plurality of shapes for a circuit layout corresponding to an image. The system can allocate a stencil buffer for the image, the stencil buffer comprising a stencil sample for at least one point of the image. A system can generate, using the stencil buffer, an indication of a number of the plurality of shapes that overlap the at least one point. The overlap indications can inform alternative placements of the plurality of shapes for the circuit layout.

The invention relates to the technical field of virtual reality image processing, and discloses a virtual reality ideological and political content self-adaptive generation method based on emotion calculation, which comprises the following steps: mapping a user physiological signal into a visual intervention weight coefficient; preloading a reference color lookup table and a target color lookup table; writing a mask identifier of the information primitive into the template buffer area in a rasterization stage; reading a template numerical value in a fragment coloring stage, if the template numerical value is matched with a mask identifier, returning the weight to zero, otherwise, keeping the weight; according to the method, pixel-level decoupling of global atmosphere rendering and local information fidelity is achieved through the template buffer area, and the problem that key information is lost due to dynamic visual style reconstruction is solved under constant computing power overhead.

A method and apparatus for rendering a computer-generated image using a stencil buffer is described. The method divides an arbitrary closed polygonal contour into first and higher level primitives, where first level primitives correspond to contiguous vertices in the arbitrary closed polygonal contour and higher level primitives correspond to the end vertices of consecutive primitives of the immediately preceding primitive level. The method reduces the level of overdraw when rendering the arbitrary polygonal contour using a stencil buffer compared to other image space methods. A method of producing the primitives in an interleaved order, with second and higher level primitives being produced before the final first level primitives of the contour, is described which improves cache hit rate by reusing more vertices between primitives as they are produced.

Systems, apparatuses and methods may provide for technology that determines a stencil value and uses the stencil value to control, via a stencil buffer, a coarse pixel size of a graphics pipeline. Additionally, the stencil value may include a first range of bits defining a first dimension of the coarse pixel size and a second range of bits defining a second dimension of the coarse pixel size. In one example, the coarse pixel size is controlled for a plurality of pixels on a per pixel basis.

Important information with respect to image generation such as computer game video generation can be lost once the full image is composed. To avoid this, a customized capture script is created for a computer game to specify what to capture, for future use, in the middle of rendering a game video frame, such as frame buffer, depth buffer, stencil buffers, etc. The script also specifies when during frame rendering the data is to be recorded. By capturing data mid-frame, object boundaries on the screen and relative distances between objects can be inferred. This information can be used in 2D-to-3D conversion, object coloring for increased contrast, object highlighting, etc.
