And i was curious to implement it manually. Here is my code to count black pixel on each column : for(int aa = 0; aa < after_shear.cols;aa++){ Mat aaTmp = after_shear.col(aa); int jumlah = 0; for(int oalah = 0; oalah < aaTmp.rows;oalah++){ for(int oalah2 = 0; oalah2(oalah,oalah2)<(oalah,oalah2)==0){ jumlah++; } } } if(jumlah==0||jumlah==1){ pspArray2.push_back(fuck2); } }  But, it gives me zero result.

Should it be the row first ?
