Soon, edit photo with text commands

August 11, 2014

edit-photos-onlineNew York, Aug 11: Struggling with photo editing software? Switch to a new technology that changes weather, time of day, season or other features in photos with simple text commands.

With a new computer algorithm developed by researchers at Brown University in the US, a picture taken in July can be made to look a bit more like in January simply by typing "more winter".

The algorithm can edit photos according to 40 commonly changing outdoor attributes, the researchers said.

"Programmes like Photoshop are really powerful, but you basically need to be an artist to use them. We want anybody to be able to manipulate photographs as easily as you would manipulate text," said James Hays, an assistant professor of computer science at Brown University.

The new algorithm uses machine learning to make all the subtle changes in colour and contrast that happen across the entire photo -- changes that would normally require a skilled photo editor to fully replicate.

To start the project, the researchers defined a list of transient attributes that users might want to edit.

To teach the algorithm what these attributes look like, the researchers compiled a database consisting of thousands of photos taken by 101 stationary webcams around the world.

Armed with the knowledge of what each attribute looks like, the algorithm can apply that knowledge to new photos.

"If you wanted to make a picture rainier, the computer would know that parts of the picture that look like sky need to become greyer and flatter," Hays explained.

A paper describing the work will be presented this week at SIGGRAPH, the world's premier computer graphics conference to be held in Canada.

In the wake of the gas leak at a factory in Visakhapatnam, the National Disaster Management Authority (NDMA) has issued detailed guidelines for restarting industries after the lockdown and the precautions to be taken for the safety of the plants as well as the workers.

In a communication to all states and union territories, the NDMA said due to several weeks of lockdown and the closure of industrial units, it is possible that some of the operators might not have followed the established standard operating procedures.

As a result, some of the manufacturing facilities, pipelines, valves may have residual chemicals, which may pose risk. The same is true for the storage facilities with hazardous chemicals and flammable materials, it said.

The NDMA guidelines said while restarting a unit, the first week should be considered as the trial or test run period after ensuring all safety protocols.

Companies should not try to achieve high production targets. There should be 24-hour sanitisation of the factory premises, it said.

The factories need to maintain a sanitisation routine every two-three hours especially in the common areas that include lunch rooms and common tables which will have to be wiped clean with disinfectants after every single use, it added.

For accommodation, the NDMA said, sanitisation needs to be performed regularly to ensure worker safety and reduce the spread of contamination.

To minimise the risk, it is important that employees who work on specific equipment are sensitised and made aware of the need to identify abnormalities like strange sounds or smell, exposed wires, vibrations, leaks, smoke, abnormal wobbling, irregular grinding or other potentially hazardous signs which indicate the need for immediate maintenance or if required shutdown, it said.

At least 11 people lost their lives and about 1,000 others were exposed to a gas leak at a factory in Andhra Pradesh''s Visakhapatnam on May 7.

The incident took place after it restarted operations when the government allowed industrial activities in certain sectors following several weeks of lockdown.

The lockdown was first announced by Prime Minister Narendra Modi on March 24 for 21 days in a bid to combat the coronavirus threat. The lockdown was then extended till May 3 and again till May 17.

Twitter has joined efforts to do away with racially loaded terms such as master, slave and blacklist from its coding language in the wake of the death of African-American George Floyd and ensuing Black Lives Matter protests.

The project started even before the current movement for racial justice escalated following the death of 46-year-old George Floyd in police custody in May.

The use of terms such as "master" and "slave" in programming language originated decades ago. While "master" is used to refer to the primary version of a code, "slave" refers to the replicas. Similarly, the term "Blacklist" is used to refer to items which are meant to be automatically denied.

The efforts to change these terms in favour of more inclusive language at Twitter were initiated by Regynald Augustin and Kevin Oliver and the microblogging platform is now backing their efforts.

"Inclusive language plays a critical role in fostering an environment where everyone belongs. At Twitter, the language we have been using in our code does not reflect our values as a company or represent the people we serve. We want to change that. #WordsMatter," Twitter's engineering team said in a post on Thursday.

As per the recommendations from the team, the term "whitelist" could be replaced by "allowlist" and "blacklist" by "denylist".

Similarly, "master/slave" could be replaced by "leader/follower", "primary/replica" or "primary/standby".

Twitter, however, is not the first to start a project to bring inclusivity in programming language.

According to a report in CNET, the team behind the Drupal online publishing software started using "primary/replica" in place of "master/slave" as early as in 2014.

The use of the terms "master/slave" was also dropped by developers of the Python programming language in 2018.

Now similar efforts are underway at Microsoft's Github and LinkedIn divisions as well, said the report.

The Covid-19 pandemic has made an unprecedented impact on the Indian businesses, particularly small and medium enterprises (SMEs) and startups. According to a joint survey by FICCI and Indian Angel Network (IAN), the pandemic has hit the businesses of around 70% startups.

With uncertainty in the business environment and an unexpected shift in priorities of the government as well as corporates, many startups are struggling to survive, it says.

In a nationwide survey on the 'Impact of Covid-19 on Indian Startups' involving 250 startups, 70% participants said their businesses had been impacted by Covid-19 and around 12% had shut operations.

The survey shows only 22% startups have cash reserves to meet the fixed cost expenses over the next 3-6 months, and 68% are reducing operational and administrative expenses.

Around 30% of the companies said they would retrench employees if the lockdown was extended too long. The 43% startups have already started 20-40% salary cuts over April-June.

Over 33% startups said investors had put the investment decision on hold and 10% said the deals had been scrapped. Only 8% startups had received funds as per the deals signed before Covid-19 outbreak, the survey revealed.

The reduced funding has forced startups to put a hold on business development and manufacturing activities, which has resulted in loss of projected orders.

The survey highlights the need of an urgent relief package for startups, including possible purchase orders from the government, tax relief and swifter tax refunds, and immediate fiscal support measures, including grants, soft loans and payroll grants.

Besides 250 startups, 61 incubators and investors also participated in the survey.

While 96% of investors accepted that their investments in startups had been impacted by Covid-19, 92% said their investments in startups would continue to be low over the next six months.

Around 59% investors said they would prefer to work with the existing portfolio firms in the coming months. Only 41% said they would consider new deals.

"A comparison of priority investment sectors before and during Covid-19 shows 35% investors are now looking at investments in healthcare startups, followed by EdTech, AI/Deep Tech, FinTech and Agri," said the survey.

Around 44% incubators surveyed said their day-to-day operations had been considerably hit by Covid-19. Most incubators are now supporting their portfolio firms by providing them virtual platforms to interact with mentors, investors and industries.

Dilip Chenoy, FICCI Secretary General, said, "The startup sector is stressed for survival at the moment. The investment sentiment is also subdued and is expected to remain so in the coming months. Lack of working capital and cash flows may lead to major layoffs over the next 3-6 months."

Indian startups needed an enabling ecosystem and flow of funds to continue operations, the survey said.

Padmaja Ruparel, President, Indian Angel Network & Co-Chair of FICCI Startup Committee, said, "In these uncertain times, as investors, we must play an important role to provide the Indian startups funding, mentoring and hand-holding support to stay afloat and come out at the other end of this crisis."

To that end, IAN recently announced a debt fund to help IAN portfolio companies raise working capital and ensure business continuity by partnering with debt providers.

This must be replicated on a wider scale, so a larger number of startups are provided the capital support to make it during these tough times, Ruparel said.
