data1=reshape(data,8,length(data)/8);%将data1中的二进制字符串转换为对应的十进制表示,并将结果重新排列为%M×N×K的三维矩阵,其中M为行数,N为列数,K为通道数。 data2=reshape(bin2dec(data1'),M,N,K);%显示转换后的图像数据imshow(uint8(data2)); 2、运行结果 左图为原图片,右图为转换成二进...
3 BW=im2bw（RGB，level）将真彩色图像RGB转换为二值图像。如果输入图像不是灰度图像，im2bw将输入图像转换为灰度，然后通过阈值化将该灰度图像转换为二进制图像。Class support（类支持）1 输入映像可以是uint8、uint16、single、int16或double类，并且必须是不透明的。输出图像BW是类逻辑的。I和X必须是二维的。RGB...
matlab官方给出的dec2bin function: functions=dec2bin(d,numBits)%DEC2BIN Convert decimal integer to its binary representation% DEC2BIN(D) returns the binary representation of D as a character% vector. D must be an integer. If D is greater than flintmax, DEC2BIN% might not return an exact...
在matlab中使用imread函数读入一幅图像,得到由图像灰度构成的uint8类型的数值矩阵,然后用fopen、fclose进行文件的读写操作,用printf函数将数值打印到TXT文档中,话不多说,上代码。 由于图像数据太大,所以先写一个测试程序,这是以十进制形式输出 %% 测试程序1 close all;clear;clc; mat=uint8(magic(4)) fid=fopen...
