find_contours(dilated, contours, WIDTH, HEIGHT, 1000);这句C代码转换成verilog

将这句C代码转换为Verilog代码需要将其拆分成多个步骤，并使用Verilog语言实现。

以下是可能的Verilog实现步骤：

1. 在Verilog中定义输入和输出参数：

module find_contours (
    input [WIDTH*HEIGHT-1:0] dilated,
    output [WIDTH*HEIGHT-1:0] contours
);

2. 在Verilog中实现初始化标记数组：

reg [7:0] visited [0:HEIGHT-1][0:WIDTH-1];
integer i, j;
initial begin
    for (i = 0; i < HEIGHT; i = i + 1) begin
        for (j = 0; j < WIDTH; j = j + 1) begin
            visited[i][j] = 0;
        end
    end
end

3. 在Verilog中实现寻找轮廓：

integer label, area, queue_front, queue_rear, k;
reg [7:0] visited_tmp, in_tmp, out_tmp;
reg [15:0] queue_x [0:WIDTH*HEIGHT-1], queue_y [0:WIDTH*HEIGHT-1];
integer x, y;

initial begin
    // 初始化标记数组
    label = 1;
    for (i = 1; i < HEIGHT - 1; i = i + 1) begin
        for (j = 1; j < WIDTH - 1; j = j + 1) begin
            visited_tmp = visited[i][j];
            in_tmp = dilated[i*WIDTH+j];
            if (in_tmp > 0 && visited_tmp == 0) begin
                visited[i][j] = label;
                area = 1;
                queue_front = 0;
                queue_rear = 0;
                queue_x[queue_rear] = i;
                queue_y[queue_rear] = j;
                queue_rear = queue_rear + 1;
                while (queue_front < queue_rear) begin
                    x = queue_x[queue_front];
                    y = queue_y[queue_front];
                    queue_front = queue_front + 1;
                    visited_tmp = visited[x-1][y];
                    in_tmp = dilated[(x-1)*WIDTH+y];
                    if (in_tmp > 0 && visited_tmp == 0) begin
                        visited[x-1][y] = label;
                        area = area + 1;
                        queue_x[queue_rear] = x - 1;
                        queue_y[queue_rear] = y;
                        queue_rear = queue_rear + 1;
                    end
                    visited_tmp = visited[x+1][y];
                    in_tmp = dilated[(x+1)*WIDTH+y];
                    if (in_tmp > 0 && visited_tmp == 0) begin
                        visited[x+1][y] = label;
                        area = area + 1;
                        queue_x[queue_rear] = x + 1;
                        queue_y[queue_rear] = y;
                        queue_rear = queue_rear + 1;
                    end
                    visited_tmp = visited[x][y-1];
                    in_tmp = dilated[x*WIDTH+y-1];
                    if (in_tmp > 0 && visited_tmp == 0) begin
                        visited[x][y-1] = label;
                        area = area + 1;
                        queue_x[queue_rear] = x;
                        queue_y[queue_rear] = y - 1;
                        queue_rear = queue_rear + 1;
                    end
                    visited_tmp = visited[x][y+1];
                    in_tmp = dilated[x*WIDTH+y+1];
                    if (in_tmp > 0 && visited_tmp == 0) begin
                        visited[x][y+1]
