形态学开运算 - MorphOpen

函数简介

对图像进行开运算(先腐蚀后膨胀),去除小噪点同时保持整体形状。

接口名称

MorphOpen

DLL调用

int64_t MorphOpen(int64_t instance, int64_t ptr, int32_t kernelSize);

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。
ptr长整数型图像指针
kernelSize整数型结构元素核大小,建议使用奇数(3、5、7等)

示例

SDK 调用

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long handle = ola.MorphOpen(0, 0);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
long handle = ola.MorphOpen(0, 0);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
handle = ola.MorphOpen(0, 0)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
long handle = ola.MorphOpen(0, 0);
cpp
var ola = com("OlaPlug.OlaSoft")
var handle = ola.MorphOpen(0, 0)
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
handle = ola.MorphOpen(0, 0)
text
.局部变量 ola, OLAPlug
ola.创建 ()
handle = ola.MorphOpen(0, 0)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var handle = ola.MorphOpen(0, 0);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
长整数 handle = ola.MorphOpen(0, 0)
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long handle = ola.MorphOpen(0, 0);

原生 DLL 调用

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

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int MorphOpen(long ola, int ptr, int kernelSize);

MorphOpen(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.MorphOpen(instance, 0, 0)

返回值

长整数型:返回处理后的图像句柄,失败返回0。

注意事项

  • 与 MorphClose 配合可实现形态学细化清理。
  • 返回的图像需调用 FreeImagePtr 释放内存。
