    copied!<p>I've got the message above, while I'm trying to run my algorithm on more than 26 frames.</p> <p>My program is in C#, with my experience with OpenCV in java(Android) I know that I need to release the matrix, do I need to do it here also?</p> <p>this is the part with the problem:</p> <pre><code> private void toolStripButton2_Click(object sender, EventArgs e) { for (int i = 0; i &lt; FRAME_SIZE; i++) { ColorImage = _Capture.QueryFrame(); if (ColorImage != null) { GrayImage = ColorImage.Convert&lt;Gray, float&gt;(); toolStripProgressBar1.Value = i; if (i == 0) { Max_G2 = new Image&lt;Gray, float&gt;(GrayImage.Width, GrayImage.Height); mainimage = new Image&lt;Bgr, byte&gt;(GrayImage.Width, GrayImage.Height); } FindMax(GrayImage.Copy()); } else { toolStripStatusLabel1.Text = "The video is too short!"; break; } } } private void FindMax(Image&lt;Gray, float&gt; CurrGray) { Image&lt;Gray, float&gt; TempImg = new Image&lt;Gray, float&gt;(CurrGray.Width, CurrGray.Height); Matrix&lt;float&gt; kernel1 = new Matrix&lt;float&gt;(new float[1, 2] { { -1, 1 } }); Matrix&lt;float&gt; kernel2 = new Matrix&lt;float&gt;(new float[2, 1] { { -1 }, { 1 } }); Point anchor = new Point(0, 0); CvInvoke.cvFilter2D(CurrGray, TempImg, kernel1, anchor); CvInvoke.cvFilter2D(CurrGray, CurrGray, kernel2, anchor); TempImg = TempImg.Pow(2); CurrGray = CurrGray.Pow(2); CurrGray = CurrGray.Add(TempImg); CurrGray = CurrGray.Pow(0.5); Max_G2._Max(CurrGray); } </code></pre> <p>1 more thing, I already tried to dispose all the matrix and images, but it doesn't work for me. What do I miss here? </p> <p>Thanks!</p> <p><strong>EDIT 1: ( Code with dispose)</strong></p> <pre><code>private void toolStripButton2_Click(object sender, EventArgs e) { for (int i = 0; i &lt; FRAME_SIZE; i++) { ColorImage = _Capture.QueryFrame(); if (ColorImage != null) { GrayImage = ColorImage.Convert&lt;Gray, float&gt;(); toolStripProgressBar1.Value = i; if (i == 0) { Max_G2 = new Image&lt;Gray, float&gt;(GrayImage.Width, GrayImage.Height); TempImg = new Image&lt;Gray, float&gt;(GrayImage.Width, GrayImage.Height); mainimage = new Image&lt;Bgr, byte&gt;(GrayImage.Width, GrayImage.Height); } FindMax(GrayImage); ColorImage.Dispose(); ColorImage = null; GrayImage.Dispose(); GrayImage = null; Thread.Sleep(100); } else { toolStripStatusLabel1.Text = "The video is too short!"; break; } } } private void FindMax(Image&lt;Gray, float&gt; CurrGray) { Matrix&lt;float&gt; kernel1 = new Matrix&lt;float&gt;(new float[1, 2] { { -1, 1 } }); Matrix&lt;float&gt; kernel2 = new Matrix&lt;float&gt;(new float[2, 1] { { -1 }, { 1 } }); Point anchor = new Point(0, 0); CvInvoke.cvFilter2D(CurrGray, TempImg, kernel1, anchor); CvInvoke.cvFilter2D(CurrGray, CurrGray, kernel2, anchor); TempImg.Pow(2); CurrGray.Pow(2); CurrGray.Add(TempImg); CurrGray.Pow(0.5); Max_G2._Max(CurrGray); CurrGray.Dispose(); CurrGray = null; } </code></pre>
