gradiosbmppromptableimage 0.0.3

gradio_sbmp_promptable_image
A webcam-compatible Gradio input image component enabling prompting with the most recently drawn bounding box and multiple points.
Installation
pip install gradio_sbmp_promptable_image

Usage
import gradio as gr
from gradio_sbmp_promptable_image import SBMPPromptableImage
import cv2

BLUE = (135, 206, 235)
PINK = (239, 149, 186)

image_examples = [{"image": "images/cat.png", "points": []}]

def get_point_inputs(prompts):
point_inputs = []
for prompt in prompts:
if prompt[5] == 4.0:
point_inputs.append((prompt[0], prompt[1], prompt[2]))

return point_inputs

def get_box_inputs(prompts):
box_inputs = []
for prompt in prompts:
if prompt[2] == 2.0 and prompt[5] == 3.0:
box_inputs.append((prompt[0], prompt[1], prompt[3], prompt[4]))

return box_inputs

def process_input(input_dict):
img, points = input_dict['image'], input_dict['points']

point_inputs = get_point_inputs(points)
box_inputs = get_box_inputs(points)

for point in point_inputs:
x, y = int(point[0]), int(point[1])
cv2.circle(img, (x, y), 2, (0, 0, 0), thickness=10)
if point[2] == 1:
cv2.circle(img, (x, y), 2, BLUE, thickness=8)
else:
cv2.circle(img, (x, y), 2, PINK, thickness=8)

for box in box_inputs:
x1, y1, x2, y2 = int(box[0]), int(box[1]), int(box[2]), int(box[3])
cv2.rectangle(img, (x1, y1), (x2, y2), (255, 0, 0), 2)

return img
