In Image Processing applications, it is often necessary to know the size of an image that is loaded or transformed through various stages. When working with OpenCV Python, images are stored in numpy ndarray. To get the image shape or size, use ndarray.shape to get the dimensions of the ima...
While converting images, apply optimization techniques like adjusting compression levels, removing metadata, or resizing images to target dimensions. This reduces file size without noticeably affecting image quality, improving performance in web applications. Leverage image mode conversions Convert images to ...

The code uses theimg_to_arrayfunction to get a NumPy array from the image and then prints the properties of the array. Note that the type of the array elements is float32. The array has three dimensions. So, this is a three-dimensional tensor. The TensorFlow framework uses suc...
When working with data science projects, I often need arrays with more than one dimension. To create multi-dimensional arrays with zeros, simplypass a tuplewith the desired dimensions: # Create a 2D array (matrix) with 3 rows and 4 columns ...
Since numpy uses C order, FITS uses fortran order, we have to write the TDIM and image dimensions in reverse order, but write the data as is. Then we need to also reverse the dims as read from the header when creating the numpy dtype, but read as is. distutils vs setuptools As of...
Image Analysis works on images that meet the following requirements: The image must be presented in JPEG, PNG, GIF, BMP, WEBP, ICO, TIFF, or MPO format The file size of the image must be less than 20 megabytes (MB) The dimensions of the image must be greater than 50 x 50 pixels an...
