BAIDU_AI开放平台_天空分割的测试

一、基本情况
目前网络服务多以Http方式直接传播数据信息。在本次调用中，首先是
开通权限
而后是鉴权
    public static class AccessToken
    {
        // 调用getAccessToken()获取的 access_token建议根据expires_in 时间 设置缓存
        // 返回token示例
        public static String TOKEN = "24.adda70c11b9786206253ddb70affdc46.2592000.1493524354.282335-1234567";
        // 百度云中开通对应服务应用的 API Key 建议开通应用的时候多选服务
        private static String clientId = "VGzQ7jWz57mBGcDTYACgbAaD";
        // 百度云中开通对应服务应用的 Secret Key
        private static String clientSecret = "RZOcID2IRUCccUGzXdihZKjaoCMTZIth";
        public static String getAccessToken()
        {
            String authHost = "https://aip.baidubce.com/oauth/2.0/token";
            HttpClient client = new HttpClient();
            List<KeyValuePair<String, String>> paraList = new List<KeyValuePair<string, string>>();
            paraList.Add(new KeyValuePair<string, string>("grant_type", "client_credentials"));
            paraList.Add(new KeyValuePair<string, string>("client_id", clientId));
            paraList.Add(new KeyValuePair<string, string>("client_secret", clientSecret));
            HttpResponseMessage response = client.PostAsync(authHost, new FormUrlEncodedContent(paraList)).Result;
            String result = response.Content.ReadAsStringAsync().Result;
            Console.WriteLine(result);
            return result;
        }
    }
最后是调用
 public class SkySeg
    {
        // 天空分割
        public static string skySeg()
        {
            string token = "24.f3ad594ec508e2830506909191535524.2592000.1602456936.282335-18132305";
            
            string host = "https://aip.baidubce.com/rest/2.0/image-process/v1/sky_seg?access_token=" + token;
            Encoding encoding = Encoding.Default;
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(host);
            request.Method = "post";
            request.KeepAlive = true;
            // 图片的base64编码
            string base64 = getFileBase64("E:/sky.jpg");
            String str = "image=" + HttpUtility.UrlEncode(base64);
            byte[] buffer = encoding.GetBytes(str);
            request.ContentLength = buffer.Length;
            request.GetRequestStream().Write(buffer, 0, buffer.Length);
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.Default);
            string result = reader.ReadToEnd();
            Console.WriteLine("天空分割:");
            Console.WriteLine(result);
            return result;
        }
        public static String getFileBase64(String fileName)
        {
            FileStream filestream = new FileStream(fileName, FileMode.Open);
            byte[] arr = new byte[filestream.Length];
            filestream.Read(arr, 0, (int)filestream.Length);
            string baser64 = Convert.ToBase64String(arr);
            filestream.Close();
            return baser64;
        }
    }

二、延伸研究
对于这样一个平台，最后如果部署为网络 服务，肯定还是走Python js等语言，所以Csharp只是简单测试一下。我想思考的问题是它的应用场景在哪里？我是否需要去做准备？然后应该去做什么准备？
使用DL去做图像增强，即使是Baidu也意识到是一个领域，但是他们很可能同样也应用场景不明，其局限应该还是“真”和“假”的区分。因为其根本，这里的增强并不是一种主观意识的正确（比如夜视、静脉穿刺、去雾等），它的容错率是很低的，如果做的不“真”，最终只能是停留在娱乐领域。但是从另一个方面来说，这个方面能力的积累却不能等到场景展现出来以后再做，至少现在就 应该有所积累。这个我是放在专门的项目中来说明的。
三、BAIDU_AI开放平台
可以看出倾向于CV，这个分类可以说是有参考价值的。
四、备注

获取Access Token

请求URL数据格式

向授权服务地址https://aip.baidubce.com/oauth/2.0/token发送请求（推荐使用POST），并在URL中带上以下参数：

  • grant_type： 必须参数，固定为client_credentials；
  • client_id： 必须参数，应用的API Key；
  • client_secret： 必须参数，应用的Secret Key；

    服务器返回的JSON文本参数如下：

    • access_token： 要获取的Access Token；
    • expires_in： Access Token的有效期(秒为单位，一般为1个月)；
    • 其他参数忽略，暂时不用;

    例如：

    {
      "refresh_token": "25.b55fe1d287227ca97aab219bb249b8ab.315360000.1798284651.282335-8574074",
      "expires_in": 2592000,
      "scope": "public wise_adapt",
      "session_key": "9mzdDZXu3dENdFZQurfg0Vz8slgSgvvOAUebNFzyzcpQ5EnbxbF+hfG9DQkpUVQdh4p6HbQcAiz5RmuBAja1JJGgIdJI",
      "access_token": "24.6c5e1ff107f0e8bcef8c46d3424a0e78.2592000.1485516651.282335-8574074",
      "session_secret": "dfac94a3489fe9fca7c3221cbf7525ff"
    }

Base64返回说明

  • 返回参数

    字段是否必选类型说明
    log_id是uint64唯一的log id，用于问题定位
    scoremap否string分割结果的灰度图，base64编码字符串。每个像素的取值范围是0-255的整数，可以近似于概率，值越大表示越可能是天空。
    labelmap否string分割结果的二值图，base64编码字符串。每个像素值是0或1，0表示背景，1表示天空。

    返回示例

    {
        "labelmap": "处理后图片的二值图base64编码字符串",
        "log_id": "1262724512684703744",
        "scoremap": "处理后图片的灰度图base64编码字符串",
        "type": "sky"
    }
