Converting Blob from an sqlite file to image

The dataset that I am working on is saved as an sqlite file, when I fetch it in matlab, the value becomes a 1 dimensional uint8 data, how will I convert this to an RGB or Grayscale image?

Hi @Maria Jeseca Baculo,

I understand that you are trying to convert a blob from an sqlite database file to an image and you have managed to get the data from sqlite database file into a matlab single dimensional array of uint8. You can reshape the array using reshape function.

Example:

sampleArr = [1, 2, 3, 4, 5];
img = reshape(sampleArr, row, size, channels); % rows*cols must be equal to size of sampleArr

I am assuming that you know the size of the RGB image (height x width x 3) you want and possibly a single image.
