imageJ marco threshold自适应阈值

该代码为imageJ marco code 将8bit灰度图片文件导入后可用此代码算出adaptive threshold

 height=getHeight(); width=getWidth(); histo=newArray(256); cutpre=0; cutnow=0; for(i=0;i<width;i++){ 	for (ii=0;ii<height;ii++){ 		v=getPixel(i,ii); 		histo[v]+=1; 		cutnow+=v; 	} } cutnow=cutnow/width/height; while(cutnow != cutpre){ 	cutpre=cutnow; 	up=0; 	down=0; 	upc=0; 	downc=0; 	for(i=0;i<256;i++){ 		if (i<cutpre){ 			down+=i*histo[i]; 			downc+=histo[i];} 		else{ 			up+=i*histo[i]; 			upc+=histo[i];} 		 	} 	cutnow=up/upc/2+down/downc/2; } print(cutnow);
