Slice-assisted super-inference for small object detection
Small object detection refers to the identification and localization of objects of relatively small size in digital images. These objects often have limited spatial extent and low pixel coverage, and can be difficult to detect due to their small appearance and low signal-to-noise ratio. Small target detection has many applications: Surveillance and Security: Identify and […]
Implementation and principles of object serialization in Python
The pickle module can implement algorithms for converting arbitrary Python objects into a series of bytes (i.e., serialized objects). These byte streams can be transferred or stored, and then reconstructed into a new object that has the same characteristics as the original object. Notice: The documentation for pickle clearly states that it provides no security […]
