The base of a pyramid was always a perfect square. This is because the western side was associated with the land of the dead. The pyramids of Egypt are all built to the west of the Nile River. The Great Pyramid of Giza points very precisely to the north. Interesting Facts about the Great Pyramids Despite the Egyptian's efforts, nearly all of the pyramids were robbed of their treasures by 1000 B.C. Because there was such valuable treasure buried within the pyramid, grave robbers would try to break in and steal the treasure. Sometimes fake burial chambers or passages would be used to try and trick grave robbers. There were often small rooms that acted as temples and larger rooms for storage. Near the Pharaoh's chamber would be other rooms where family members and servants were buried. The walls were often covered with carvings and paintings. Because it took so long to build them, Pharaohs generally started the construction of their pyramids as soon as they became ruler.ĭeep inside the pyramids lays the Pharaoh's burial chamber which would be filled with treasure and items for the Pharaoh to use in the afterlife. Scientists estimate it took at least 20,000 workers over 23 years to build the Great Pyramid of Giza. The pyramid would get slowly built, one block at a time. It is believed that thousands of slaves were used to cut up the large blocks and then slowly move them up the pyramid on ramps. How the pyramids were built has been a mystery that archeologists have been trying to solve for many years. It's estimated that this pyramid was made from 2.3 million blocks of rock weighing 5.9 million tons. When it was first built it was over 480 feet tall! It was the tallest man-made structure for over 3800 years and is one of the Seven Wonders of the World. The largest is the Pyramid of Khufu, also called the Great Pyramid of Giza. The sun god stood on the mound and created the other gods and goddesses. 
These pyramids represent a mound that emerged at the beginning of time. Later pyramids have more sloping and flat sides. Archeologists think that the steps were built as stairways for the pharaoh to use to climb to the sun god. Some of the earlier pyramids, called step pyramids, have large ledges every so often that look like giant steps. Deep inside the pyramid the Pharaoh would be buried with all sorts of items and treasure that he may need to survive in the afterlife. As part of their religion, the Egyptians believed that the Pharaoh needed certain things to succeed in the afterlife. These rectangles are then each pooled with max- or avg-pooling to calculate the output.The pyramids were built as burial places and monuments to the Pharaohs. Given an 2D input Tensor, Spatial Pyramid Pooling divides the input in x² rectangles with height of roughly (input_height / x) and width of roughly (input_width / x). al.: Spatial Pyramid Pooling in Deep Convolutional Networks for Visual Recognition Principle
These stripes are then each pooled with max- or avg-pooling to calculate the output. Given an 2D input Tensor, Temporal Pyramid Pooling divides the input in x stripes which extend through the height of the image and width of roughly (input_width / x). Sudholt, Fink: Evaluating Word String Embeddings and LossFunctions for CNN-based Word Spotting Principle The purpose of this fork is to continue maintenance of this package and post on Pypi
I (Eric Musa) take no credit for writing the Pyramid Pooling code, but could not find any information on Revidee to provide proper credit. NOTE This repo has been forked from Revidee's original (which seems to no longer be under maintenance) to publish on Pypi. This Module implements Spatial Pyramid Pooling (SPP) and Temporal Pyramid Pooling (TPP) as described in different papers.
