public class TSRPass extends Object
TSRPass is a class responsible for performing super-resolution rendering on input images. The class creates a TSRPass object and provides methods for initialization, rendering, and releasing resources.

Usage:

  1. Create a TSRPass object using the constructor.
  2. (In glThread) Initialize the TSRPass object by calling the init(int, int, float) method.
  3. (In glThread) Perform super-resolution rendering on an input opengl texture by calling the render(int) method.
  4. Release resources when the TSRPass object is no longer needed by calling the release() method.

Example:

 // Create a TSRPass object using the constructor.
 TSRPass tsrPass = new TSRPass();

 // The code below must be executed in glThread.
 //----------------------GL Thread---------------------//
 // Init TSRPass
 tsrPass.init(inputWidth, inputHeight, srRatio);
 // If the type of inputTexture is TextureOES, you must transform it to Texture2D.
 int outputTextureId = tsrPass.render(inputTextureId);

 //----------------------GL Thread---------------------//

 // Release resources when the TSRPass object is no longer needed.
 tsrPass.release();

    • TSRPass

      public TSRPass(TSRPass.TSRAlgorithmType algorithmType)
      Creates a TSRPass object for super-resolution.

      This method must be executed after TSRSdk.init(long, int, TSRSdk.TSRSdkLicenseVerifyResultCallback, TSRLogger), TSRPass.TSRAlgorithmType

      参数:
      algorithmType - The TSRAlgorithmType enum value representing the algorithm running mode to be used. It can be either STANDARD (fast mode) or PROFESSIONAL (quality mode). STANDARD mode prioritizes better performance in terms of speed, possibly sacrificing some result accuracy. PROFESSIONAL mode prioritizes result accuracy, even if the running speed is slower.

    • init

      public boolean init(int inputWidth, int inputHeight, float srRatio)
      Init TSRPass object for super-resolution. This method must be called in the GLThread.
      参数:
      inputWidth - The width of the input image
      inputHeight - The height of the input image
      srRatio - The magnification factor for super-resolution.
      返回:
      true if the initialization is successful, false if the opengl es version is lower than 3.1

    • setParameters

      public void setParameters(float brightness, float saturation, float contrast, float sharpness)
      Set the parameters of the rendering operator. It needs to take effect after init(int, int, float) is called.
      参数:
      brightness - The brightness level to apply. Valid values are between 0 and 100, with a default value of 50.
      saturation - The saturation level to apply. Valid values are between 0 and 100, with a default value of 50.
      contrast - The contrast level to apply. Valid values are between 0 and 100, with a default value of 50.
      sharpness - The sharpness factor to apply Valid values are between 0 and 100, with a default value of 0.

    • render

      public int render(int textureId)
      Performs the super-resolution rendering operation on the input image. This method must be performed in the GLThread.
      This method applies the super-resolution rendering process to the input image, improving its quality. The processed image is rendered onto a texture within the TSRPass object. And the return is the texture's id.

      NOTE: The type of the texture corresponding to the textureId you pass in must be texture2D.
      参数:
      textureId - The OpenGL textureId of the input image that needs to be processed for super-resolution. The corresponding texture is a texture2D texture.
      返回:
      The textureId of the texture2D after super-resolution rendering, which is stored inside the TSRPass object. The size of the output texture is (inputWidth * srRatio, inputHeight * srRatio).

    • render

      public int render(int textureId, float[] transformMatrix)
      Performs the super-resolution rendering operation on the input image with a specified transform matrix. This method must be performed in the GLThread.

      This method applies the super-resolution rendering process to the input image, improving its quality, and uses the given transform matrix to manipulate the image during the rendering process. The processed image is rendered onto a texture within the TSRPass object. And the return is the texture's id.

      NOTE: The type of the texture corresponding to the textureId you pass in must be texture2D.

      参数:
      textureId - The OpenGL textureId of the input image that needs to be processed for super-resolution. The corresponding texture is a texture2D texture.
      transformMatrix - A float array representing the transform matrix to be applied to the input image during the rendering process. The matrix should be in column-major order and of size 16.
      返回:
      The textureId of the texture2D after super-resolution rendering and applying the transform matrix, which is stored inside the TSRPass object. The size of the output texture is (inputWidth * srRatio, inputHeight * srRatio).

    • release

      public void release()
      Releases the resources.
      This method should be called when the TSRPass object is no longer needed, to free up the memory and other resources.
