i using visual 2010 (c++) opencv 2.3.1 construct code background subtraction using mog2. shown in full code here works noise. can suggest on how reduce noise. 1 (thanks him) has told me increase size of kernel instead of using morphological function: void morphops(mat &thresh){ mat erodeelement = getstructuringelement( morph_rect,size(2,2)); //3x3 mat dilateelement = getstructuringelement( morph_rect,size(1,1)); //8x8 erode(thresh,thresh,erodeelement); erode(thresh,thresh,erodeelement); dilate(thresh,thresh,dilateelement); dilate(thresh,thresh,dilateelement); } but not know how because still beginner. 1 (thanks him) has suggested solving contours problem noticed if run code " two tips. seems taking 1 point many contours. try averaging them. damp on time. example damped_x=damped_x*0.9+real_x*0.1; part not know how it. you can see portion of code containing contours in following section, intentionally used have blobs on other small...

i need parent key it's child keys represent list of latitude , longitude in recyclerview. guess need latlngsmodel item in populateviewholder inside firebaserecycleradapter no matter don't right. i loops trough parent keys child keys many parent keys has, , adds list... the json structure: { "users" : { "0057242b-81e2-4f97-bca7-b671212614ba" : { "email" : "kalle@hotmail.se", "waypoints" : { "-kh9uaph5nmljexaua5g" : { "-kh9uaph5nmljexas2s" : { "latitude" : 111, "longitude" : 111.1 } }, "-khb1vjqudo90vxj9xch" : { "-khb1vjqudo90vxj9xci" : { "latitude" : 222.1, "longitude" : 222.11 }, "-khb1zykbwgxm9spnie9" : { "latitude" : 222.2, "longitude" : 222.22...
