You can get a mask of the tank by thresholding at some value, like 40 or 100 or whatever works well
In this tutorial, we discuss the history of image dehazing, show how to set an image dehazing task up in a notebook, and then examine 7 different techniques …
Functionality being removed or changed The regionprops function uses new equation for circularity Behavior change 4-4 Starting in R2023a, the regionprops function uses a new equation to calculate circularity. The new equation removes a bias that caused the computed circularity to be too high for ...
Peak Signal-to-Noise Ratio or PSNR is an objective metric that measures the degree of signal distortion between a haze-free image obtained by a dehazing algorithm and the ground truth image. Mathematically it is defined by the following, where “DH” represents the dehazed image obtained from ...
1. How to form MOS? The suggestion given by ITU-T Rec BT.500 is to "establish a non-expert group with ≥15 people". After getting the video's annotations by the raters, first calculate the correlation between each person and the overall mean, and remove the scores with low correlation...
figures, actions, and scenes to expand data; on the right; Respectively, the anti-interference ability of lighting, noise and motion blur is improved. We calculate the consistency loss of the original data and the enhanced data through the network output to improve the robustness of the model....

This setting is used to increase the volume of the entire audio file. The value should be in dB. Never keep this setting at more than 10 dB. It will distort your audio at the really loud places. To calculate this value: Suppose you need 2 times the volume of your source file in you...
