DollarPedestrianDetectionCode
All the files (image data bases, annotations, detection results) should be put in some standard directories: $code/ is the directory where you unpack the matlab code.
You have to have one subdirectory for each db, for instance, you need one for INRIA: $code/data-INRIA/. The names are standard, they're defined in some matlab file.
Inside the particular db directory, you need to have
- the videos subdirectory, containing more subdirectories and the ".seq" files with the images
- the annotations subdirectory, containing more subdirectories and the ground truth annotations
- the res subdirectory, containing more subdirectories with the results of the detections obtained running various algorithms
Annotations are in the format: (x0, y0, deltaX, deltaY, confidence). The confidence value is used to plot the ROC curves. I don't know if the top-left corner is (0,0) or (1,1).
Operations you want to do
Set the db you're working on
[pth,setIds,vidIds,skip,minHt] = dbInfo( 'inriatest' )
Show db images with annotations
vbbPlayer
Compute the ROC curves for the specified algorithms, on the current db
dbEval
Display images with GT annotations, the detections of a specific algorithm and their evaluation (true positive, false positive, etc.)
dbBrowser
You should set some parameters in dbBrowser.m, such as which algorithm's results you want to plot and if there's some padding to be removed (line 3). Padding should be removed for INRIA dataset only, as far as I know.
rPth=[pth '/res/HOG']; % directory containing results thr=[]; % detection threshold resize={100/128, 42/64, 0}; % controls resizing of detected bbs
This file writes plots in $code/results and data in $code/eval.
How to evaluate the results of your algorithm
You should repeat for all the images in a given set:
Read one or more imags from a ".seq" file and write it to a regular file:
Is = seqIo( 'data-INRIA/videos/set00/V000.seq', 'toImgs', '.', 1, 0, 2, 'png' )
input seq file command dest directory frames to skip first frame last frame format
