We develop end-user software using MATLAB for Quantitative Biomedical Image Processing & Analysis.  Brief summary of these packages is provided below.  The MATLAB codes can be made available for pursuing collaborative research.
This MATLAB based software segments complex glomerulus boundary in histopathological images using an integrated method, based on Gabor filter bank based textural segmentation, statistical F-testing, and distance transform.  We have developed our method to segment glomerular boundaries in five common histopathological stains: hematoxylin & eosin, periodic acid-Schiff (PAS), Gömöri's trichrome, Congo red (CR), and Jones silver.  Our method localizes the exact glomerular boundary with mean sensitivity/ specificity of 0.88/0.96 and accuracy of 0.92 on 1000 images.  The H&E and trichrome images show the most specific performance as compared to manual annotation, with a mean sensitivity/specificity of 0.87/0.97.  Jones silver staining is least specific but also most sensitive, with mean sensitivity/specificity of 0.90/0.92.  CR and PAS staining fall between the other contenders, with sensitivity/specificity of 0.88/0.95 each. We will be happy to share our code and raw input data for pursuing collaborative research.
Computational pipeline for segmenting the glomerular boundary. (A) Hematoxylin and eosin stained glomerular tissue image.  (B) Grayscale version of the image shown in A.  (C) Gaussian blurred image of B.  (D) Intensity image of the first principal component of the Gabor filter bank outputs using as input the image shown in C.  (E) K-means clustering was used to find final Gabor boundary.  (F) F-testing examines the entire image for similarity with E, and outputs 0 or 1 for each pixel.  (G) Morphological noise removal for the image in F.  (H–I) Respective binary masks obtained from F-testing and Gabor filter bank were distance transformed.  (J) Intensity image of a spatial weighting intensity map obtained from A.  (K) Heatmap of an average of intensity images in H–J. (L) Final segmentation after thresholding shown using green.  The segmentation obtained from initial Gabor (see E) is shown using black.  The green boundary depicts improved detection of glomerulus.
This C++ based software automatically segments fluorescence microscopy images for a given resolution.  Users can control the desired levels of detail in the segmented images by tuning a resolution parameter while segmenting using our software.  In the resulting segmentation, low resolution leads to larger segments, and high resolution leads to smaller segments.

This MATLAB based software takes as input any 2D DIC microscopy image of cells, and automatically segments the cells by press of a button.  It can also take fluorescence images of the cells as additional input, and can provide a table, listing the cell area, fluorescence mean and variance, and structural heterogeneity of each cell.  A snap of the software is provided below.
This python based software predicts the probability defining how easily a new peptide sequence can be synthesized when such a sequence is considered for synthesis in a chemistry lab.  If the prediction probability is low, the software suggests minimally modified sequences that can be synthesized with ease.  Potential application of this software can be exploring new molecular targets in cancer.
First Four Steps:
Step1: Upload training & test sequences
Step3: Performance analysis
Step4: Estimation of the stability likelihood of the amino acids in the sequence
(Left) Performance of the proposed method (NBC) in predicting how easy a peptide is synthesizable.  A total of 161 peptides were considered for learning.  Information obtained from the peptide sequences alone allows our method (NBC1) to achieve prediction with AUC = 0.89.  Additional information on the peptides, such as their sequence length, hydrophobicity, charge, oxidation, and β-sheet formation, in addition with their sequence information, improves prediction of the method (NBC2) with AUC = 0.97.  (Right) Proposed method outperforms commercially available software Peptide Companion (PC).  Same peptide sequences as considered in the previous example were considered.  NBC performs prediction with AUC = 0.97, while PC was only able to achieve an AUC of 0.83 in predicting synthesis feasibility of a peptide.
