**First, Power over Ethernet Technology** Power over Ethernet (PoE) is a technology that allows the delivery of both electrical power and data signals through a single Ethernet cable. This innovation enables IP-based devices such as IP phones, wireless access points, and security cameras to receiv ---MORE---
**First, Power over Ethernet Technology** Power over Ethernet (PoE) is a technology that allows both data and power to be transmitted over standard Ethernet cables. It enables the delivery of direct current (DC) power to network devices such as IP phones, wireless access points, and surveillance c ---MORE---
The 74LS138 is a 3-to-8 line decoder that allows for the decoding of three binary input signals into eight output lines. It is commonly used in digital circuits to expand the number of available output lines from a microcontroller or other digital system. The pin configuration of the 74LS138 include ---MORE---
The 74LS138 is a 3-to-8 line decoder that is commonly used in digital circuits for address decoding and I/O port expansion. It features three address input pins (A0 to A2), three enable inputs (G1, /G2A, /G2B), and eight active-low output lines (Y0 to Y7). The pin configuration allows the chip to de ---MORE---
After the face test discussed earlier, the face is extracted and saved for training or recognition. The following code demonstrates how to extract a face: Face Preprocessing Once you have a face image, it’s tempting to use it directly for recognition. However, doing so without proper prep ---MORE---
After the face test mentioned earlier, the face is extracted and saved for training or recognition. The code for extracting the face is as follows: Face Preprocessing Once you have a face image, it can be used for face recognition. However, if you try to use an unprocessed image directly, you ma ---MORE---
