计算两帧之间的相似度 - CalculateFrameSimilarity ​

函数简介 ​

计算两帧之间的相似度。

接口名称 ​

CalculateFrameSimilarity

DLL调用 ​

c
double CalculateFrameSimilarity(int64_t instance, int64_t frame1, int64_t frame2);

参数说明 ​

参数名类型说明
instance长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
frame1长整数型第一帧图像句柄。
frame2长整数型第二帧图像句柄。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
double value = ola.CalculateFrameSimilarity(0, 0);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
double value = ola.CalculateFrameSimilarity(0, 0);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
value = ola.CalculateFrameSimilarity(0, 0)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
double value = ola.CalculateFrameSimilarity(0, 0);
cpp
var ola = com("OlaPlug.OlaSoft")
var value = ola.CalculateFrameSimilarity(0, 0)
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
value = ola.CalculateFrameSimilarity(0, 0)
text
.局部变量 ola, OLAPlug
ola.创建 ()
value ＝ ola.CalculateFrameSimilarity(0, 0)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var value = ola.CalculateFrameSimilarity(0, 0);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
双精度 value = ola.CalculateFrameSimilarity(0, 0)
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
double value = ola.CalculateFrameSimilarity(0, 0);

原生 DLL 调用 ​

cpp
CalculateFrameSimilarity(instance, 0, 0);
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int CalculateFrameSimilarity(long ola, int frame1, int frame2);

CalculateFrameSimilarity(instance, 0, 0);
python
from ctypes import CDLL, c_int, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
ola.CalculateFrameSimilarity(instance, 0, 0)

返回值 ​

返回值说明
（返回值）双精度浮点数：相似度（0-1，1表示完全相同）。
