] = 0 Why is this statement 101:301 instead of 100:300? I think it should be masking mask is more than the original image left and right up to 1, so mask masks about 2 more than the original image, up and down also more than the original image 2. Then 100 of the original image will naturally correspond to 101 of the mask, the same 300 of the original image will naturally correspond to the mask of 301.3. When the floodfill_mask_only is set, the original image will not change and will only fill th

The function for setting ROI on an image is:Cvsetimageroi (iplimage* src,cvrect rect); src represents the source image, and rect refers to the ROI region.If you want to cancel the ROI region, use the function:Cvresetimageroi (iplimage* src); This function cancels the ROI region on SRC.Example:#include "

The 2D up-right Rectangle Class The class represents a 2D rectangle with coordinates of the specified data type. Normally, Cv::rect ~ cv::rect_ From the above definition can be found at least two points: first, the class Rect_ class t

A small feature in the project that needs to implement a background substitution for a specific area of the video, write down a function like this: void Bgreplace (mat dst, MATBG, Rect rec) { assert (Dst.size () ==bg.size ()); ASSERT (dst.depth () = = Bg.depth ()); DST (REC) = BG (rec). Clone ();//Can be deep and shallow } function, use rec to specify the area to be replaced, replacing DST's value for that region with the value of this zone for BG.But, unexpectedly, this function d

ROIs pooling as the name implies, is a pooling layer, but also for the ROIs pooling;The whole ROI process is to pull these proposal out of the process, get the size of a unified feature map.What is ROI?

Respect the author and reprint the website. ROI Align is a regional feature aggregation method presented in MASK-RCNN this paper, which solves the problem of region mismatch (mis-alignment) caused by two quantization in ROI pooling operation. Experiments show that the replacement of Roi Pooling with ROI Align in the te

Whether in the picture display or in the process of finding corners in the optical flow method, we all encounter the ROI thing. Its role is to allow us to focus on the image or an area of the current video frame (which we call an area of interest) instead of processing the entire image or the entire video frame, not only eliminating unnecessary error disturbances, but also reducing the amount of computation. Next, describe how to set

The modern marketing approach allows you to track your ROI at every step of the campaign. Long story short, if you don't optimize your ROI on the campaign, then you're likely to throw the money in vain. Google Analytics, and the range of other tools, allows you to calculate where you are, what your money is and what causes this to happen. There are three things you need to do first before you can really sta
