Methods
10015 dermatoscopic images were collected from HAM10000 within a period of 20 years from different sites from Austria and Australia. The Australian site stored the images in Excel and PowerPoint databases. The Australian site collected images before the beginning of the digital cameras and they stored metadata and images in various formats during various time periods.
Every PowerPoint had consecutive dermatoscopic and clinical images of a calendar month and every slide had a single image along with a text field and a unique lesion identifier. An automated approach was used as the amount of data was huge. The Python package was used for accessing the PowerPoint files and obtaining the content.
Before digital cameras were introduced, the images at the Department of Dermatology in Vienna were kept as diapositive. The histopathologic diagnoses demonstrated that high variability between and within sites such as typos, various dermatopathology terminologies, several diagnoses on every lesion or on uncertain diagnosis. The cases that had uncertain collisions and diagnoses were excluded. The diagnoses were unified and seven generic classes were formed and ambiguous classifications were avoided.
The seven generic classes were selected for simplicity and regarding the intended use as a dataset for diagnosing pigmented lesions by machines and humans. The seven classes included over 95% of the pigmented lesions that are examined daily clinically. These are explained in our HAM10000 Dataset assignment help in Australia.
Manual Quality
Final manual validation and screening were performed on the images for excluding cases having the following attributes:
- Type: The overview and close-up images, which were nor=t removed along with automatic filtering
- Quality: The images that remain out of the focus or had very disturbing artifacts such as constructing gel bubbles.
- Identifiability: The images that have potentially identifiable content including jewelry, garment, or tattoos.
- Content: The non-pigmented ocular and lesions, mucosal or subungual lesions
The remaining cases were also reviewed for accurate color reproduction and if essential a corrected through manual histogram correction.
Working with Datasets
Machine learning regarding cancer detection is not possible minus data. However, there are just a few datasets to train a neural network for classifying skin lesions. But the HAM10000 dataset is a dataset, which contains a huge collection pf dermatoscopic images of the pigmented skin lesions.
The HAM10000 dataset comprises 10000 images of 7 kinds of skin cancer. Similar to other datasets, it might have duplicates and errors and thus the data must be preprocessed first.
