fpga高分辨率二值图像连通合并代码

以下是一个基于FPGA的高分辨率二值图像连通合并的参考代码：

module ImageConnectivityMerge (
  input wire clk,
  input wire reset,
  input wire [7:0] image_in,
  output wire [7:0] image_out
);
  
  // 定义图像尺寸
  parameter WIDTH = 640;
  parameter HEIGHT = 480;
  
  // 定义最大连通分量数量
  parameter MAX_LABELS = 256;
  
  // 定义连通分量标签宽度
  parameter LABEL_WIDTH = 8;

  // 寄存器定义
  reg [LABEL_WIDTH-1:0] labels [0:HEIGHT-1][0:WIDTH-1];
  reg [LABEL_WIDTH-1:0] label_counter;
  
  // 连通分量合并逻辑
  always @(posedge clk) begin
    if (reset) begin
      // 初始化
      for (int i = 0; i < HEIGHT; i = i + 1) begin
        for (int j = 0; j < WIDTH; j = j + 1) begin
          labels[i][j] <= 0;
        end
      end
      label_counter <= 0;
    end else begin
      // 连通分量合并
      for (int i = 0; i < HEIGHT; i = i + 1) begin
        for (int j = 0; j < WIDTH; j = j + 1) begin
          if (image_in[i*WIDTH+j] == 1) begin
            if (i == 0 && j == 0) begin
              labels[i][j] <= label_counter;
              label_counter <= label_counter + 1;
            end else if (i == 0) begin
              if (labels[i][j-1] != 0) begin
                labels[i][j] <= labels[i][j-1];
              end else begin
                labels[i][j] <= label_counter;
                label_counter <= label_counter + 1;
              end
            end else if (j == 0) begin
              if (labels[i-1][j] != 0) begin
                labels[i][j] <= labels[i-1][j];
              end else begin
                labels[i][j] <= label_counter;
                label_counter <= label_counter + 1;
              end
            end else begin
              if (labels[i][j-1] != 0 && labels[i-1][j] != 0) begin
                if (labels[i][j-1] == labels[i-1][j]) begin
                  labels[i][j] <= labels[i][j-1];
                end else begin
                  labels[i][j] <= labels[i][j-1];
                  for (int k = 0; k < HEIGHT; k = k + 1) begin
                    for (int l = 0; l < WIDTH; l = l + 1) begin
                      if (labels[k][l] == labels[i-1][j]) begin
                        labels[k][l] <= labels[i][j-1];
                      end
                    end
                  end
                end
              end else if (labels[i][j-1] != 0) begin
                labels[i][j] <= labels[i][j-1];
              end else if (labels[i-1][j] != 0) begin
                labels[i][j] <= labels[i-1][j];
              end else begin
                labels[i][j] <= label_counter;
                label_counter <= label_counter + 1;
              end
            end
          end
        end
      end
    end
  end
  
  // 输出图像
  always @(posedge clk) begin
    if (reset) begin
      image_out <= 0;
    end else begin
      for (int i = 0; i < HEIGHT; i = i + 1) begin
        for (int j = 0; j < WIDTH; j = j + 1) begin
          image_out[i*WIDTH+j] <= labels[i][j];
        end
      end
    end
  end
  
endmodule

这是一个简单的Verilog代码示例，用于在FPGA上实现高分辨率二值图像的连通合并。代码中使用了一个二维数组作为标签存储器，通过遍历输入图像的每个像素，根据连通关系进行标签合并，并输出合并后的图像。请注意，此代码仅为示例，实际应用中可能需要根据具体需求进行调整和优化。
