使用文檔中提供的相同示例代碼,您所需要做的就是更改 main 方法,如下所示:
public static void main(String[] args) throws Exception{
? ? // Create a new file object for the first file and get bytes from file
? ? File file = new File("C:\\Users\\ihene\\Desktop\\my-photo.jpg");
? ? byte[] buff1 = getBytesFromFile(file);
? ? // Create a new file object for the second file and get bytes from file
? ? File file2 = new File("C:\\Users\\ihene\\Desktop\\esan-caleb.jpg");
? ? byte[] buff2 = getBytesFromFile(file2);
? ? // Data needed to use the Face++ Compare API
? ? String url = "https://api-us.faceplusplus.com/facepp/v3/compare";
? ? HashMap<String, String> map = new HashMap<>();
? ? HashMap<String, byte[]> byteMap = new HashMap<>();
? ? map.put("api_key", "dam4ZdTkSsZOUAiR4oQpP3DRnjEz1fcD");
? ? map.put("api_secret", "0MOCfpum1Lec06EMOzuJPOEa_EhM4Ttg");
? ? byteMap.put("image_file1", buff1);
? ? byteMap.put("image_file2", buff2);
? ? try {
? ? ? ? // Connecting and retrieving the JSON results
? ? ? ? byte[] bacd = post(url, map, byteMap);
? ? ? ? String jsonStr = new String(bacd);
? ? ? ? // Parse the JSON and get the confidence value
? ? ? ? JSONObject obj = new JSONObject(jsonStr);
? ? ? ? double confidence = obj.getDouble("confidence");
? ? ? ? System.out.println(confidence);
? ? } catch (Exception e) {
? ? ? ? e.printStackTrace();
? ? }
}
只需將PATH_TO_FILE_1、PATH_TO_FILE_2、YOUR_API_KEY、 和替換YOUR_API_SECRET為適當?shù)闹导纯?。它?yīng)該有效。
我使用兩張臉部屬于同一個人的圖像和另外兩張不同臉部的圖像測試了 API。這是我得到的前者的輸出:
{"faces1": [{"face_rectangle": {"width": 156, "top": 210, "left": 142, "height": 156}, "face_token": "1ee9de6d362b0c8c1bf240a70fbf3eac"}], "faces2": [{"face_rectangle": {"width": 156, "top": 210, "left": 142, "height": 156}, "face_token": "0a7c539f3603aa744ee18c65acc224a8"}], "time_used": 531, "thresholds": {"1e-3": 62.327, "1e-5": 73.975, "1e-4": 69.101}, "confidence": 97.389, "image_id2": "Fc64vrBtETVmP2cS+BoW/Q==", "image_id1": "Fc64vrBtETVmP2cS+BoW/Q==", "request_id": "1569184566,0cc04f1a-1495-4316-928c-1efe7d6836dc"}
請注意,這里的置信度是97.389。文件稱,“置信度越高,表明兩張臉屬于同一個人的可能性就越高。” 所以,這符合我們的預(yù)期。對于后面具有不同面孔的圖像,輸出如下:
{"faces1": [{"face_rectangle": {"width": 156, "top": 210, "left": 142, "height": 156}, "face_token": "c7d8561f0235a99d9b060750c7a9c3c7"}], "faces2": [{"face_rectangle": {"width": 75, "top": 44, "left": 53, "height": 75}, "face_token": "ad87092cb593128c015c2e2221b962f2"}], "time_used": 533, "thresholds": {"1e-3": 62.327, "1e-5": 73.975, "1e-4": 69.101}, "confidence": 53.993, "image_id2": "MiZOf00hrq7OmAxc3+n7sg==", "image_id1": "Fc64vrBtETVmP2cS+BoW/Q==", "request_id": "1569185082,0bfd0a0f-a376-4dac-92bd-924c34ef76ed"}
此處,置信度為53.933。
