OpenCV中Mat像素访问和赋值的问题

android开发中使用opencv,如何解决内存泄漏问题?

大家好, 目前开发一个android项目,需要用到opencv,便于图像数据的利用, 于是就直接调用了opencv的camera进行frame采集。 使用过程中发现,画面会越来越卡,最后导致程序崩溃,一查看是native内存 累积2个G,从而崩溃掉了。 因为不太了解opencv,使用方式是在网上的教程里学的,release()也写了,并不能 解决内存问题,所以请教一下,是否有办法解决这个问题。 谢谢~

OpenCV Mat对象使用数组数据块初始化

OpenCV的官网介绍Mat对象,共列出了25种基本的初始化方法。 其中,对于使用数组数据块的初始化方法官方给出的例子是 ``` double m[3][3] = {{a, b, c}, {d, e, f}, {g, h, i}}; Mat M = Mat(3, 3, CV_64F, m).inv(); ``` _但是我这样初始化我的Mat对象,数据为什么不对呢 double m[][3] = {{1, 2, 3}, {3, 0, 9}, {1, 3, 8}}; Mat M(3, 3, CV_8U, m); 这样的方式初始化的Mat对象数据根本就不是m数组里面的数据啊。请教高手解答啊 _
