No matter what type(s) of photography you like to pursue, mastering exposure is key to creating successful images. While it can be tempting to use your camera's screen to judge exposure, that display ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The UHI implementation of the equality operator only compares the histogram type, binning and counts. ROOT histograms have way more properties, like drawing options, and even more crucially they store ...

When using Python OpenTelemetry (OTel) to record histogram metrics with unique integer attributes, all recorded histograms are showing a static start_time_unix_nano value in the OpenTelemetry logs.

time complexity cannot be more than O(n) You cannot use divisibility operation. Because they are the most brute-force solutions anyone could have that of on the first go. I had to wait for almost 2 ...

Abstract: Image segmentation plays an important role in image analysis and computer vision system. Among all segmentation techniques, the automatic thresholding methods are widely used because of ...

Abstract: In this paper, we propose a reversible data hiding (RDH) method based on a two-dimensional (2D) histogram and generalized histogram shifting (GHS). First, a cover image is decomposed into ...
