一、关键技术

1、人脸识别
它是一项根据人脸特征用于身份识别的生物技术。通过摄像头或者摄像机采集的面部信息,然后在已存储的照片中检测和匹配人脸,从而进行身份识别的技术。

2、人脸美化
人脸美化也是美颜SDK基于AI技术的一大创新,随着人们审美水平的不断提高,对照相质量的要求也越来越高。后期处理已经无法满足广大爱美人士的需求,实时人像处理也就应运而生。人脸美化技术可以在保留人物面部特征的情况下,对人像进行差异化一键美化处理,这项技术被广泛应用于美颜sdk中,这项技术现在受到越来越多人的喜爱。

@interface MHOpenDemoUITests : XCTestCase

@implementation MHOpenDemoUITests

  • (void)setUp {
    // Put setup code here. This method is called before the invocation of each test method in the class.

    // In UI tests it is usually best to stop immediately when a failure occurs.
    self.continueAfterFailure = NO;

    // In UI tests it’s important to set the initial state - such as interface orientation - required for your tests before they run. The setUp method is a good place to do this.
    }

  • (void)tearDown {
    // Put teardown code here. This method is called after the invocation of each test method in the class.
    }

  • (void)testExample {
    // UI tests must launch the application that they test.
    XCUIApplication *app = [[XCUIApplication alloc] init];
    [app launch];

    // Use recording to get started writing UI tests.
    // Use XCTAssert and related functions to verify your tests produce the correct results.
    }

  • (void)testLaunchPerformance {
    if (@available(macOS 10.15, iOS 13.0, tvOS 13.0, *)) {
    // This measures how long it takes to launch your application.
    [self measureWithMetrics:@[[[XCTApplicationLaunchMetric alloc] init]] block:^{
    [[[XCUIApplication alloc] init] launch];
    }];
