About DermaCompare

DermaCompare is a revolutionary skin cancer screening platform that enables physicians to identify and monitor changes in their patients’ skin characteristics. DermaCompare was developed by Emerald Medical Applications, a digital health startup. Emerald specialises in image processing software infrastructure solutions for an extensive range of applications for diverse medical unmet needs. Emerald’s technology utilizes the knowledge of military image processing and big data analytics to improve the analysis of medical images for the benefit of patients and the medical community alike.

DermaCompare is the first application of Emerald’s technology and innovation and it is set to revolutionise the world of dermatology and aid the early detection of skin cancer.


The challenge

The detection of skin cancer in its early stages is crucial for patient survival Dermatologists around the world are still using manual techniques, which are time  consuming expensive and inaccurate. The last innovation in this field was adopted by dermatologists about fifteen years ago  and it is called Total Body Photography (TBP). TBP is a set of 25 photos that cover the  entire skin surface of the patient. Dermatologists recommended doing TBP every year,  comparing the photographs and detecting the key differences. This solution is still very inaccurate because the human skin is dynamic, constantly moving and changing. Consequently a manual diagnostic procedure is both limited and expensive, and thus Inaccessible to most of the population.


Our technology originated from the concepts applied by the Israeli Air Force and the intelligence services who use auto aerial photo diagnostics to track collateral damage  after engaging the enemy. This means that the technology has the ability to detect and  compare changes in imagery and then conduct analysis and comparison at a very high  precision level.  This technology and ability are responsible for the fact that missiles can hit targets that  are hundreds of miles away. Now Emerald has applied it to facilitate the early detection  and diagnostics of skin cancer, in order to both prevent and cure it. It has subsequently  been upgraded by the Emerald development staff to improve performance even further. DermaCompare applies innovative technology focusing on these key elements:

1. Easy to use off the shelve imaging technologies (every smartphone or digitalcamera)

2. Unique proprietary algorithms, which enable automated image processing for  identifying and registering skin moles. These can be pictured by any kind of  camera including that inside a mobile phone.

3. Automated skin mole registration and anchoring together with a  multidimensional database for documentation and real-time retrieval of data  regarding skin moles and lesions.

4. Utilizing big data and predictive analytics to provide physicians with real time  data on patients’ skin, history and changes in moles or lesions.

5. Harnessing the power of crowdsourcing of skin imaging and Cloud Computing for  dermatologists, providing a low cost, user-friendly end-user interface.

Skin cancers are a common and usually low-grade malignant growth of the skin cells. Skin cancer usually starts from cells that begin as normal skin cells and transform into abnormal cells that have the ability grow in an uncontrolled manor. The majority of skin cancers do not have the potential to metastasize to other parts of the body and threaten the patient’s life.

Skin cancers divide in to three types: the two most common types being basal cell carcinoma and squamous cell carcinoma. The third kind is called melanoma and it is less common, although more dangerous, than the other two varieties.

Melanoma is a type of skin cancer, which forms from melanocytes, the cells that produce the dark pigment, melanin, which is responsible for the color of skin. These cells predominantly occur in skin, but they can also be found in other parts of the body, including the bowel and the eye. Melanoma can originate in any part of the body that contains melanocytes.
Melanoma is particularly common among Caucasians, especially northern and northwestern Europeans, living in sunny climates. There are higher rates of melanoma in Oceania, North America, Europe, Southern Africa, and Latin America. 420 Million people worldwide have a high risk of getting melanoma.
This geographic pattern reflects the primary cause of skin cancers i.e. exposure to ultraviolet light (UV) in conjunction with the amount of skin pigmentation in the population.
Melanoma is less common than other skin cancers. However, it is much more dangerous if not found in the early stages. It causes the majority (75%) of deaths related to skin cancer. Globally, in 2012, melanoma occurred in 232,000 people and resulted in 55,000 deaths. Australia and New Zealand have the highest rates of melanoma in the world.
The signs of melanoma are atypical moles. That is why it is so important to get to know the skin very well and to recognize any changes in the moles on the body. People who do self-exams and dermatologists look for the moles that are different by the ABCDE signs – Asymmetry, Border, Color, Diameter and Evolving.
The most common site for atypical moles are women’s legs and men’s backs. 60% of melanomas occur because of a new mole, while 40% are the result of a mole that has changed.
The detection and diagnosis of melanoma is still done manually with the recommendation that every person should know their own skin and check it once a month. Dermatologists do the same check manually which is time consuming and inaccurate.
Once an atypical mole is found, a skin biopsy is performed to confirm the diagnosis; in some cases, biopsies of areas other than the skin may be needed. For example, if melanoma has already been diagnosed on the skin, nearby lymph nodes may be biopsied to see if the cancer has spread to them.
The treatment of melanoma includes surgical removal of the tumor. If melanoma is diagnosed in an early stage, while it is still small and thin, and if it is completely removed, then the chances of a cure is high.
The likelihood that the melanoma will come back or spread depends on how deeply it has gone into the layers of the skin. For melanomas that come back or spread, treatments include chemotherapy and immunotherapy, or radiation therapy. The five-year survival rate in the United States is as high as 91%.
