使用__android_log_print打印Opencv Mat、Android NDK的内容

#include <android/log.h>

#define LOG_TAG "MyApp"
#define LOGD(...) __android_log_print(ANDROID_LOG_DEBUG, LOG_TAG, __VA_ARGS__)

#include <opencv2/core/core.hpp>
#include <android/log.h>

#define LOG_TAG "MyApp"
#define LOGD(...) __android_log_print(ANDROID_LOG_DEBUG, LOG_TAG, __VA_ARGS__)

void printMat(cv::Mat& mat) {
    LOGD("Printing Mat:");
    LOGD("Rows: %d", mat.rows);
    LOGD("Cols: %d", mat.cols);
    LOGD("Type: %d", mat.type());
    // 打印Mat的像素值
    for (int i = 0; i < mat.rows; i++) {
        for (int j = 0; j < mat.cols; j++) {
            LOGD("Pixel at (%d, %d): %d", i, j, mat.at<uchar>(i, j));
        }
    }
}
