To read BMP files in TensorFlow, you can use the tf.io.decode_bmp() function. Here's the step-by-step process:

  1. Load necessary libraries:
1
2
import tensorflow as tf
import matplotlib.pyplot as plt


  1. Read the BMP file using tf.io.decode_bmp():
1
2
image_raw = tf.io.read_file('path_to_bmp_file.bmp')
image = tf.io.decode_bmp(image_raw)


image_raw holds the binary content of the BMP file, and image represents the decoded image as a tensor.


You can also specify additional arguments in decode_bmp() as needed, like channels for the number of color channels.

  1. Once you have the image tensor, you can visualize it using matplotlib:
1
2
plt.imshow(image.numpy())
plt.show()


This will display the image.


Here's the complete code snippet:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
import tensorflow as tf
import matplotlib.pyplot as plt

# Step 1: Read the BMP file
image_raw = tf.io.read_file('path_to_bmp_file.bmp')
image = tf.io.decode_bmp(image_raw)

# Step 2: Visualize the image
plt.imshow(image.numpy())
plt.show()


Make sure to replace 'path_to_bmp_file.bmp' with the actual path to your BMP file.
