Proposed_Algorithm (Input: Image from the dataset)
Read_image as
for to 5
  (, , , ) = two_dimensional_wavelet_decomp().
   = Histogram ()
Obtain concatenated histogram of size , by concatenating five
  histograms (, , , and ) obtained in Step .
Compute feature vector (of size ) = Probabilistic_principal_component_analysis
Input the feature vector as obtained in step into a KNN or ANN model for
   classification of images.
