bcExpt1123 / transition.html

Last active June 18, 2025 23:40

This HTML code creates an interactive canvas animation featuring particles that radiate from the center. Clicking the canvas resets the particles, which follow dynamic paths with randomized velocities. The Particle class manages their movement, updating every 20 milliseconds for an engaging visual experience.

bcExpt1123 / face_swapper.py

Created June 6, 2025 02:35

A Python script that swaps faces between two images using OpenCV. It detects faces with Haar cascades, optionally refines alignment with a DNN-based facial landmark detector, applies affine transformation, and blends the source face into the destination image.

	import cv2
	import numpy as np

	def swap_faces(source_image, destination_image):
	source_img = cv2.imread(source_image)
	destination_img = cv2.imread(destination_image)
	face_cascade = cv2.CascadeClassifier(cv2.data.haarcascades + "haarcascade_frontalface_default.xml")
	source_gray = cv2.cvtColor(source_img, cv2.COLOR_BGR2GRAY)
	destination_gray = cv2.cvtColor(destination_img, cv2.COLOR_BGR2GRAY)
	source_faces = face_cascade.detectMultiScale(source_gray, scaleFactor=1.1, minNeighbors=5, minSize=(30, 30))
