Context We would like to create a mobile application that takes pictures of Belgian vehicle official document, send them on a server to processed them with OCR (Tesseract) to extract relevant information. We previously posted a job description for this subject. However, we refined the scope of the job because previous one was too ambitious and not accurate enough on how we wanted to work on. We have decreased the scope of the job, but with more details on how to proceed. Before developing the complete stack, we need to check if the document recognition is feasible or not, what processing should be done. We have identified several steps to be done : 1) Define the image processing and the Tesseract configuration required to extract relevant information from a scanned document. 2) Maybe a training phase for Tesseract. 3) Define the image processing to correct problems coming from smartphone’s picture (wide-angle lens, parallax, screwing…) Here we will focus on the first step only. However, if the collaboration is good and the results are good, we will keep working on the next steps with the hired person. What is asked The approach we would like to follow is : - Using Tesseract’s confidence score to determine a several image processing methods, - Using a key - value method to extract the relevant fields. You can see that on the attached documents, information are prefixed with a key (C.1.3, P.1. …) It means that the preprocessing phase is an iterative process. Several OCR passes are used in loop with different image-preprocessing parameters filters ; best result is selected by confidence. Tesseract provides confidence in OCR result for each recognized word. You’ll have to: - Define several image processing, - Write a script to preprocess an image (as above) and provide the recognition of the relevant information (as hash). For information : during our first tests, we find out that using a leveling on a grey-level image, with a Tesseract trained for French gave interesting results. How to process We will provide you several scanned document to use as inputs. As they are official documents, we will provide them only after we agree to work together. The sample images here are for information and their quality is poor. Better pictures, non obfuscated, will be provided to you before working on. We have also detected restrictions on the value fields (alphanumeric, numeric, list values ...) Deliverables You should provide us : - The script ( our preference is python, tell us if you have another preference), - The configuration of Tesseract, - The processed images, - Documentation on how to install, run the script, the dependencies… - Information about stable errors. We hope to not have stable errors in Tesseract recognition. But if we face this issue, it won’t mean the project will be refused. It means that we’ll have to do another training step. In fact, we are trying to find out the specific font used on the document in order to train Tesseract for this font. We’ll validate your findings by processing the images with the provided script and running the OCR against the processed images. Other non-functional specifications - The OS should be Ubuntu, - You’ll have to use the latest Tesseract version, trained for French, - The script should be in python, - The only requested interface is command line.

This is not a face recognition project. This is a specialized computer vision solution for a very specific market. I need a Computer Vision expert to look over code I have written in Java/Android/OpenCV and suggest some improvements ASAP. Respond ONLY if you have experience refining computer vision algorithms and can sign an NDA and have a look at my work TODAY. Thank you.

We are looking for an experienced OpenCV/Cuda developer for a fun time-sensitive project. The candidate needs to work in Windows with a CUDA enabled graphics card and OpenCV 3.1. Visual Studio IDE. The candidate must have knowledge of computer vision and needs to be familiar with the OpenCV documentation at http://docs.opencv.org/3.1.0/index.html#gsc.tab=0 The work involves tweaking and optimizing three OpenCV/Cuda samples for real-time video processing and adding UDP sockets to communicate results to other applications. We will provide sample files at project start, including UDP socket code, and a project direction. The work is relatively simple for someone experienced but it is very time sensitive. The project starts immediately and needs to be completed by the end of the month. The candidate needs to remain available until September 8th for revisions and to modify the code as needed. Task 1 involves object segmentation and sending data via UDP in three steps: fg/gb segmentation using CUDA sample, clustering fg pixels into separate objects, detecting centroid, bounding box and number of pixels for each object and sending this data via UDP. Task 2 is taking a CUDA optical flow sample we created and read some data off of it and sending the data across via UDP socket. Some drawing functions required. Task 3 involves face detection and adding a visual overlay onto one or more faces. Also for this we have sample code that only needs to be tested optimized. Please respond only if you are experienced in OpenCV 3.1, real time computer vision processing of video and immediately available. The project is available for one or three separate candidates -- one for each task described. Please indicate any preference.

Seeking an expert in using OpenCV and dlib for facial landmark detection and facial feature morphing to create filtering algorithms ONLY for a new iOS app that applies beauty filters to selfies. The rest of the app (UI, front end) will be developed by another developer. Must speak fluent English and communicate status on a daily basis. This may turn into an ongoing project.
