Overlaying an image on an overlaying image
Let’s say I have the frame coming from the camera. There is an image, that I would like to put on this frame so its perspective changes according to how the frame changes. I was able to achieve that using the object tracking with homography but here is the deal – overlaid image obstructs all the objects present on the frame. So for example if there is a person on that frame in the spot where this image should be located the person would not be visible. Is there any algorithm or a ML model that can help displaying the obstacles in the area where image will be? I tried using CV2 tools like findContours with dilation and stuff like this, but unfortunately it did not lead to a desired result.
Trouble detecting/removing two watermarks that vary location across image dataset
Good afternoon, all
How do I compare a template sketch to an image of a manufactured part?
I have a template image that is used as the baseline to determine where parts are soldered onto a circuit board. I cannot guarantee the images to be the same size or scale. The baseline image is provided to me by an outside source and I solder the parts myself. An image of the soldered board is taken by me. I want to quickly check for mistakes – parts that were supposed to be placed but weren’t, parts that were supposed to be skipped but weren’t, etc.
I would prefer to have a bounding box over the erroneous parts. I have attached two images that portray the images in question (I cannot provide the real images per my jobs’ policy).PCB
Template
Boxes in red indicate a part I am not supposed to place, and green indicates a part I should be placing.
I was following the information here. I attempted to use the Structural Similarity Index. This did not pan out well due to the images being very different from one another.
I do not think a dense vector representation, but this spits out a similarity score rather than exposing any mistakes that were made.
Ideally, I can produce the output from the SSI method to show what issues were missed.
How to detect different symbols in a picture with overlapping
l have a picture with some information about the milestone of each project. Each milestone is marked in the diagram with unique symbol. In the picture we have different trianlges or squares with different colors.
